I just made a pair of whoopie slings. My first set. Min usable distance is 18" and max is 12' 6". This is with a 10" bury on 7/64 Dynaglide. I will be testing them with Canoebie on Sat. Caneobie do you have a spare set of tree huggers? I have some straps I can use but im not sure if they will stretch bad or not. Find out tomorrow night. Hmm need to update my profile to include Whoopie Slings for suspension. I have enough rope left to make a set of UCR's as well. Not sure how long they will be yet. At least 10' each. Now I just need to find 2 trees about 33' apart reallly test these things.
