Tying a Hennessy

[slowhike]

another idea that came to mind that might help keep the loop around the tree in place = wrap a wee bit of shock cord around the straps close to the tree, while there is no tension it should pull the HH tree huggers together with enough force to at least keep them from sliding - with tension, either sitting or in the HH the shock cord would simplly expand with the tree huggers
I don't know, just an idea, i have yet to try it out.
If anyone gives it a shot, post a response with pics, might work out!

true... that may add just enough tension to keep it from sliding.
i had thought of putting an alligator clip on each end of a short piece of shock cord to use to help hold the webbing on those rare occasions that i have to use a tree so big that i can't reach around.
that same cord could be used for your suggestion too.

I just use a couple of slip knots. Easy to get out when its cold and wet and not a hard knot to tie. But then I did motify my huggers

I've used slipknots on a biner before...works just like your ring. Very convenient. I was worried about it binding or slipping but it was never a problem. I never tried it in the rain, though.
