Does anyone have a suggestion for camp stove?  I am leaning towards the MSR Whisperlite International.  I like the "burn any fuel" feature and it looks like it folds up pretty compact.  I welcome any suggestions

Good stove.  Doesn't simmer as well as some of MSR's other stoves.  Will sputter a bit above 10,000 feet (High pressure in the fuel tank will help mitigate both simmer and sputter a tad).  Might want to look into a trillium base if you plan to put in down on something other than rock (or other hard surface).  The rounded wire feet will pretty readily sink in soft soil/sand.  You can assist on heat distribution across the bottom of your pan with a diffuser plate (should be able to find one for about $5.00).  I think there is one that uses the term "scorch buster."  Try backpacker's panty ... they have them without the wire needed for the outback oven.

I had two whisperlites, but I had problems eventually with both of them.  I used them for a long time, but went to something completely different, a snow peak giga power stove that uses butane canisters.  I actually still liked my Peak 1 Coleman--almost better than the whisperlite.  They all work and it really boils down to do you like to use white gas or canisters.  I thought the option of being able to use different gases would be a plus also, but in reality, I never used anything but white gas with the whisperlite.  

I've had whisperlite stoves since near the beginning. The new internationale is quite robust- the shaker jet makes all the difference. As DD notes they don't simmer very well, but they are good at throwing out efficient btus. Wire legs won't be a problem if you use the heat reflector they sell with the stove.

A year ago I picked up a canister stove- MSR pocket rocket- much quicker and easier to use. really small and light but difficult in the wind and close to useless if it gets cold.

I travel with either a Simmerlite or a DragonFly as my primary stove.  My back-up stove is a Peak 1 ... generally the "all-in-one" rather than the component equivalent.  The Coleman stoves are generally superior to other stoves for simmering.  They just tend to be a bit more bulky.

As I recall, the Snow Peak Giga has a roarer-type burner like the DragonFly ... at least that's the configuration of my white-gas version.  Good burner, but typically a bit noisy.

The snow peak white gas (not to be confused with the giga which is a iso-butane stove) has a "whisperlite" style generator so it is not as loud as the dragonfly, a little more complicated as it has one more knob...and the base is not as big as the dragon fly... Both the dragon fly and the snowpeak white gas are fabulous simmers and more packable the the coleman stoves....I have run them all....the dragonfly has way more hours on it in my book but i have high hopes for the snowpeak product due to its quietness...

Do you want a stove that you can grow into or a stove that just boils water?

Is it only going to be used for Canoe Camping?

Iso Butane stoves dont care much for cold temperatures, winter camping in the future....late fall trips...how do you feel about the canisters and waste stream?

White gas is a very available fuel domestically....I have only once heard a story where the multifuel aspect of a stove came in handy...well sort of...a buddy and his friend ran out of fuel and "resorted" to the JD in an MSR XGK (a high altitude snow melter) and ended up melting the spatula and frying pan in the canyonlands of UT....

They are tools, and it all depends what you want to do with it and how much you want to spend...and how much you want to fuss with it...

Got my first Whisperlite in the 90's, I like pancakes and I gave it away after I used a friends MSR Firefly and then the Dragonfly came out it was a no brainer, but the noise does grate on a being...thats why I am moving to the above...isobutane is convenient though too but you pay for that cup of quick coffee ;)

There are a lot of options out there....whitegas, isobutane, alcohol, solid fuel, wood....StOOOOOves!

I guess I'm the exception, but I like the coleman feather 442.  I carry two of them.  They're reliable and quiet. I love the quiet.  Some of the whisperlites, etc, sound like a jet engine revving up, IMO.

Good point.  The feather 442 is actually the more recent manifestation of the Peak 1 (which I believe is out of production).  

If you are still interested in a multi-fuel model, the 442 also comes in a Dual-Fuel model (white and auto gas).

All of these models use the later configuration of the Peak 1 (Model 400B), including single level control.  (The original Peak--Model 400A--had 2 levers ... one for fuel flow and one for air mixture.)  Later production in this series are labeled Peak 1 Feather 400.

BTW:  Only the MSR DragonFly and XGK models use the "jet engine" burner. (I'm omitting the FireFly model, since it went out of production about 30 years ago.)

OK.  I was lazy and had to go dig out the Snow Peak.  Well, you are right (and I am right).  My model does indeed have the "waffle plate" style burner elements, like the Whisperlite stoves (altough the overall burner head is just about the size of a DragonFly).  However, my model (both on the stuff sack and fuel bottle) is labeled Snow Peak Giga Power WG Stove.  Maybe I should use the Snow Peak on the next trip ... 4 legs might be better than three.

These posts are all helpfull  :D and have given me some great points to think over.  I think mostly it will be used to get a percolater going on cold mornings before we go out laker fishing.  It will be used for canoe trips primarily but I would also like to take it on some high altitude backpacking trips.  I am willing to sacrifice noise for compactness and boil speed but it needs to be able to cook and simmer too.  Maybe I am asking too much  ::) but I will keep looking.  Thanks again for all the help.

The four legs aint better than the three for the pot pith IMO; I suppose it is a bit hard to switch up the perspective after being so darn spoiled by the dragon fly....it is issue of the decibels for now, it packs down a bit smaller too. Your right your right. You know though I still wish I was a machinist ::) Consider the glades; I think it could be some fun...but I will draw the line at becoming bait ;)

So how high altitude are we talking?  Colorado high, Denali high ... a bit more than that?  The noise versus compact is the reverse ... the smaller the stove, generally the louder it is.

Give us a heads up when you get your list narrowed.  I'd bet someone around here has some feedback on particular models that might be useful.

Marlin -

So, how many stoves to you have?

dd

I think I am sold on the dragon fly now.  Watched a few videos on youtube and it does look like a pain to get the whisperlite to simmer.  I am not sold on the top of canister stoves seems like they have a high center of gravity and could easily get knocked over.  Anyway the dragon fly looks like the bees knees, though pricier.  

DD - colorado high so not much over 14k.

Since it mostly peaks that push to 14K, its more likely that you'd be camping/cooking at something more like 12K.  But the MSR XGK EX is actually listed as the high-altitude version of their stove.  In reality, it is the same burner and they have run a portion of the fuel feed line over the top of the burner to pre-heat the fuel before it gets to the burner.  However, you can achieve much of the same effect with the DragonFly by using the wind screen, even when its not windy.  It will help reflect heat back toward the burner assembly which will also help warm the fuel.  Another advantage of using the wind screen is that you can conserve fuel because less heat gets dissipated via air movement.  The effect improve dramatically if your pot just fits inside the wind screen.  The MSR 2 liter titanium pot is just about perfect for this (but also pricey).  It has the additional advantages of quick heat transfer and light weight.  One downside is that it transfer heat so quickly that food will have a tendency to scorch on the bottom of the pot if you don't stir with some frequency.

dd

Check into the MSR Simmerlite and the Brunton Optimus stoves before you buy.  I used to use a Dragonfly but these two are my primary stoves now.  Both simmer well, but the Brunton is about as good as it gets for fine-tuning the heat.  Both are quieter than a Dragonfly though the Brunton is the noisier of the two.

I'm known to be somewhat of a gourmet kinda guy on the trail but I also travel hard, so versatility and light weight are key to me.  The Brunton is like cooking on your stove at home and the Simmerlite is about as light as you can get for a white gas/multifuel stove that still has adequate simmer control.  It's a pretty good tandem.

It that the Brunton Optimus Nova or one of the other models?

The Optimus burner look nearly identical to the DragonFly ... but you've got to love those swing out feet.  And its not like you're going to damage the pump on a trip ... one of the few that's nearly all solid metal!

dd

About six years ago just before I pulled the plug on the purchase of my MSR dragonfly I bought a Optimus....think it was a nova...the persuasion that snowdog is speaking of. Made it through one trip (a long weekend) as I was tearing it down after every meal to unclog the jet; the same fuel was running through the whisperlite without issue. The first stove I ever owned was an Optimus, a great simmer. I have a lot of hours on the MSR plastic pumps and they are without question bullet proof, even though they are plastic...

A good simmering stove has a method of fuel control reasonable close to the jet, like on the peaks, dragonfly, optimus, and snow peak giga wg. The msr dragonfly, optimus(svea), and the old msr firefly have a cone style generator/burner and that is what makes the noise, a good tried and true design but loud. The whisterlite/simmerlite and coleman style burner has a tube generator and burner design which quiets them down a bit; but the whistlerlite/simmerlite lacks the jet control near the jet (it is back on the fuel pump) so they simmer like doodie...good stoves but not simmers....lite weight and efficient water boilers...the snow peak giga white gas sorts some of that out...I just dont have the hours on it yet to know whether of not I can place it higher on my charts than the dragonfly...my dragonfly has been in service for over 250 trail days without any issue versus the 20 on the snowpeak...but I have hope ::)

12,000....any of these stoves will work...and a windscreen will make them more efficient and a heat diffuser will make them more user friendly-DD is right Back packer pantry has a nice one that goes with there outback oven, another fun and nifty gadget that requires a well simmering stove.

pretty much any backpacking stove on the market will fit your requirements - choose your fuel type, and sort out from there.

I live in Colorado and backpack some for hunting.  I've used my Jetboil (iso-butane cannister stove) enough times camping at 11,000" at frosty temps with no issues ( not sure what the lowest temp was - might have been approaching 20) - if you want to go cannister, there are a couple of newer models that have been tricked out to run efficiently at colder temps and higher altitudes.

Only other stoves I have are a Coleman Peak 1 and Feather 442, which also work under those conditions -

I've taken all of them on Quetico canoe trips at one time or another

main difference is the type of fuel - cost per use,  messisness, and volume.

oh, I forgot about one other stove - a burner that sits on top of the 1# propane cannisters, that I use occasionally - cheap and effective as far as the stove goes, and somewhere in the middle as to fuel. I've used it on weekend canoe trips here, but not in Quetico - too heavy and bulky overall.

all of the empty cannisters can be recycled - simple enough to punch a hole with a nail in the butane cans, and shoot holes in the green colemans

I will say, that for ease of use, no mess-no fuss, fuel efficiency and compactness, I like the Jetboil best

Yup, the Optimus Nova.  Still noisy, but somewhat quieter than a Dragonfly.

My Dragonfly constantly clogs which is why I replaced it in the first place.  Field-stripping and cleaning it on a nearly daily basis got old fast.  When it's running right it's a great stove.  Mine's got to be defective somehow because I know many others have had great reports on them.

I had clogging troubles on my earlier MSR stoves, largely resolved when they switched to the shaker jet. My "pre shaker jet" solution was to bring a little squeeze bottle of alcohol for priming.

There is no silence as fine as the silence born upon turning closed the valve of the svea 123 for the first cup of morning coffee.

I am with you, the Peak 1 is so simple and quiet. Mine fits in the coffee pot. I have been in camps where the the stoves attached to bottles were used but when they were packaged up I could not see enough space saving to warrant the hassle. Part of the Peak 1 is fuel storage. Duel fuel is my choice, the multi fuel would never hold pressure very long while cooking. With the duel fuel Peak 1 it is pumped, lit and pumped again and is good until running out of fuel. The tank warms up as you cook and keeps the pressure up. I find it best to fill it while tilting it so you can see when it is 90 percent full. The extra airspace allows for much better performance.

In Canada the fuel canisters are considered toxic waste and costs the parks extra money when left in their trash.

Trangia!  Nothing is quieter.  Nothing is easier.

I've seen the same problem with older MSR stoves, pre shaker-jet.  I took my Whisperlite winter camping once, it leaked from the valve and hasn't worked since.  I suspect it's due to two different metals in the valve assembly.  Stripped & lubed - still broke.

Don't get me wrong, MSR stoves are still tops in my book for most uses.  The assembly & process daunted a couple of my buddies to the point where they wouldn't set it up or turn it on.  Once I showed them the Trangia suddenly everyone makes coffee!    ::)

Do not get the UL Trangia model that doesn't have the full windscreen.  It sucks.  Either of the other two models.

The only downside is that I have to be careful about the pots I buy as the pot-stand options are limited.

Do not use MSR fuel bottles for Trangia fuel.  The fuel will ruin the lid.

The best part of the Trangia is that you can walk away and not burn through a whole bottle of fuel.  The burner only holds a couple oz of fuel so if that burns out it's no big deal.

Preacher- What other stoves do you use or have you used? With these EtOH stoves... really how much control does one have; they are pretty much on or off right? Now the Triangia can burn the solid fuels, EtOH, and the wind screen can be messed with to burn wood and duff...right? Do you run an Outback Oven?

I do love the dragon fly for it's relaibility and control.  

"So Mad_Mat -- you are more likely to take the Jetboil to QP rather than the Peak or Feather 442?"

yes - mainly because its lighter and takes up less volume overall, as compared to a 442 and exra fuel bottles and cooing pot.  Solo, or for two people, it will be the Jetboil - more than two people, I'd take the 442 and use a bigger pot for boiling water, which is all I do anyway.

While the Jetboil is less mess and fuss (i.e. no refilling the stove from fuel bottles), that isn't really much of an issue for me - its mostly the weight and bulk

Preacher- What other stoves do you use or have you used?

MSR - 2 generations of Whisperlite
Primus - I forget the model, but it was like a jet engine
Coleman - The burner screws on to tall/tippy propane cans
Home Made Alcohol Stoves - Neat but too fussy for my preference.
And of course the Trangia.

Right off the top I'm against cannister stoves for weight overhead + environmental issues.

Trangia has excellent control with their simmer ring/snuffer.  The main advice I'll give is that you can't be afraid of fire.  It's a little tricky to use the simmer ring, but you get used to it with practice just like most gear.

I used to use the OO for years, but haven't recently.  I have seen others do it, had a very nice pizza in Temagami one day!

What's old is new again.  I think this kind of assembly was first used on a Primus No. 5 stove (circa 1912).

The actual burner jet assembly was the precursor of today roarer-type burner.

I'd like to get one of those for the old svea123 to tame the roar.
wait a minute. price is 100-250? The craftsmanship looks beautiful, BUT.

The Svea123 is a great stove.  Actually the first stove I ever used.  Buddy's dad had one from days of yore.

$100 for a quality stove is about right.

The price range he is quoting is for ONLY the "quietizer cap" (designated as either a dragon tamer or an omnidawg).

I think I'll try crafting my own version.  Did a trial last night with the bottom of a can that had a concaved bottom.  Worked pretty well at a lower setting, but I need to create the interior piece to prevent blow-back at higher fuel rates.  This might be reduced somewhat if I added a few more/larger holes ... I as using a 5/64ths drill bit to punch the holes.

This adaptation may also make a dragon fly a bit more wind tolerant.

dd

BTW:  Svea 123 stoves now go for more like half the price you quoted, if you shop around, but they are also built with lesser quality materials than earlier stoves.

the 123 i'm using is pretty old. got it from a co-worker who many years ago hitch-hiked all over the states and europe with it. it was basically free.  :)

Well, at least I've got a couple of models to look at.  Both the Primus No 5 and the later American made Vesuvius use a similar "technology."  The Primus has an internal baffle, but the Vesuvius does not.

At any rate, one trial result I didn't mention was that the decibels were cut by at least 2/3rds.

Time ... that's what retirement is for!  More time to tinker, more time to plan trips, more time to play with/develop maps.

BTW:  I'm still working on a home grown fire-piston ... something less bulky than the commercial model I have.

dd

For my warm weather trips (assuming there is no burn ban) I carry two stoves.

1. Snowpeak Giga with some canisters (but not enough canisters to do all the cooking... maybe about 50%)

and

2. a "Bush Buddy" twig stove.   (You need to Login or Register
The twig stove can boil water with just a hand ful of twigs. I like it because were I go canoe camping I can almost always find a hand full of dry twigs and if it's so wet that I can't I can either resort to a pre-bagged stash of twigs or go with the Snowpeak. With the twig stove I can never run out of fuel. And it only weights 5.5 oz. It can be a bit laborious compared to the snow peak but it's not too bad.  I like it. especially for long duration trips where it can save lots of heavy fuel.

Yeah, I can hear, I mean see the difference. Wow, your doing a good job of stacking them holes. Not sure I could keep them so straight even with a drill press. You'd think MSR would pick up on this.

I think if you re-read, you'll find that the parts (except for a 1" section of copper tubing) are manufactured parts for the Primus 111 stove.  

Yeah.  You are right ... my tests on creating these parts myself didn't result in the holes all cleanly aligned.  I think I'd need to make a jig to get that level of accuracy.

As for MSR looking into this adaptation, I would think it to be a no-brainer.  The roarer-type burner is a design that is prominent in Primus stoves, so for MSR to use the "flame/sound disperser" would not likely involve any more copyright/patent issues than the burner itself.  Of course, I didn't run my project long enough to determine if there is a fuel efficiency difference or the BTU output is modified, but I would doubt any significant impact.
