i changed over my hh asym to whoopies. use biners with nylon straps. no slip, easy fast set up. still the best sleep in town!

My hammock came with adjustment buckles.  In the setup instructions it tell you if the webbing does not go through straight it will slip and they are correct.  Occasionally I will be in a hurry and make a fast adjustment and not pull in line with the straps and when I set on the hammock it is a letdown. I have never had them slip when they were straight.
I started off without carabineers.  That required removing the straps from the buckels to feed it through the eye in the strap.  Carabineers make set up much easier and faster but what works even better is Dutch clips.  I also have sewn some Dutch hooks on to my hammock to make attaching my under quilt faster and snugger. 

I've been doing some research on suspension systems for hammocks or tensioning systems for (ridge) lines.  It seems that many of the discussions always seem to revert to one of two choices when it comes to (a) easily adjustable and (b) light weight:  whoopee slings and O-rings.  A whoopee sling works on the same principle as the Chinese finger "handcuff" and the double O-ring is a pincher system.

They seem simple enough to use and should save a lot of set-up time and fiddling. 

Anyone have any experience with these systems?  Any "slippage when wet" issues?  Do you use the double O-ring w/ w/o carabiner?
