Here's a THREAD
and here's a pic:
This was my "A-Ha!" moment. I've been wrestling with this since I started hanging as I regularly deal with giant oaks and have hung many nights from giant coastal redwoods. With this as a fallback plan I've never had to do anything bigger than 7ft straps and 7ft whoopies. Picture a marlin spike where the pic shows a buckle.... done deal.
If it's not obvious I like whoopies better. If the straps get damp I just leave em in an outer pocket to dry out. FWIW I've never left components behind, and that's not meant to sound rude, just sayin...
