i actually changed from whoopies to the strap and buckle system from brandon and like it better for a few reasons
1. no tree straps to worry about, so that is one less thing to haul around and forget at camp
2. i find the adjustment easier than with the whoopies
3. the set up/take down time is quite a bit quicker which i really like
4. i find i have a wider variety of tree distance's that i can use them with, both closer together and farther apart
I just switched to a suspension from Dutchware with whoopie hooks . I like that the whoopies are attached to tree straps so I don't loose (forget) them, but I can unhook from hammock if straps are wet and pack them away from hammock. The original suspension was too bulky and too wet when it rained.
I use the "all in one" from whoopieslings.com but the cinch buckle isn't bad you just have to separate the buckles. he does a video to show you on his site.
