I've been using whoopie slings since day 1 and I'm considering switching to beckett hitching my hammock continuous loop to my tree straps. I'm researching some straps but hoping to get some thoughts before buying.

So far I've narrowed it down to ripstop Venoms or spider 1.5. Anyone know which of the 2 have less stretch? Or at least do they have less stretch that spider polys? I'm asking because I've been in a situation where I saw excessive stretching in either my 15' spider polys or whoopie slings (not sure which) and would like to avoid if possible.

Also, should 12' be enough? I'm worried about larger trees eating up the length especially if the trees are far apart. I don't know how to extend if I really needed to... What do you guys do for backup in this case?
