I never could tie one of those leaders right, so I went a different path. I found some #1 size nickel sleeves that the # 25 wire will go thru 2x. I slide 2 sleeves on the wire and then add swivel/snap-lock and DOUBLE back thru the 2 sleeves.
I take a needle nose pliers and make a 90 degree bend after the first sleeve. I pull wire to desired loop size and then crimp the 2 sleeves. The last thing I do is cut the wire that is bent at the angle as close to the crimped sleeve as my little side cutters will allow.

If the edge is a little sharp, I hit it with a small diamond coated file I got from Harbor Freight as a hobbyist set.

When I'm all done I do a pull test like KF does.
So far they've held up that way. Just an alternative IF you can't do it the way KF described for whatever reason.

Right on Nanda, me too.  I am a bit lazy and just forked over the cash for a few titanium leaders. 

As long as we're talking losing fish ....  Last August I was on Sunday Lake in the Q trolling a deep diver (Excalibur?).  My rod was nearly lost as it pulled from my hands.  I'm thinking I'm snagged but soon a very heavy fish mosied out into deeper water.  I had a heck of a time pulling it up to gain ground on my real.

I tell my bowman to paddle us toward the lee shore as the breeze was taking us out into the lake.  As soon as the boat turns my line went slack.  I never lost tension but the barbless treble just pulled
free.

What upsets me the most is I never got a glimpse of it.  About a 1/2 hour earlier I boated a 25 inch trout.  Was this a trout?  Maybe a northern.  But, it could've been a huge walleye too.  I'll never know and the fish haunts me.  Didn't Captain Ahab go through something similar?  Maybe on every trip up there I will have to pass through Sunday and troll the southern shore in search of my "whale". 

While I'm chasing down that criimper let me relay that I put Suffix brand 8lb braid on my SPIREX reel. Big mistake. I lost several lures, at least one or two on every trip I've taken this year. The line is really not suited to troll as it frays and breaks off quite easy whenever it's trolled or a fish shakes to throw the lure (and cuts it). Maybe I just bought some old stock (it was cheap)? It's off my SPIREX and the reel will be spooled with 10lb braid Fireline.

Good points Westwood. Question for you: When you tighten your improved cinch knot or whichever knot you use, do you gently and slowly pull the standing line or the tag end? Also, what brand of 20lb braid do you have spooled up? I'm just curious -- I realize that there are several options out there and everyone has their favorite. Any advice would be great.

I've been using 20# suffix 832 and palomar knots for about 5 years and have never had a knot fail. will be switching to lighter power pro next year. made in usa.
