I plan to hike the PCT this coming year. I know I won't be able to hang all the time and it is possible I might have to go to ground as much as 25% of the time. Assuming those numbers are correct, I will be able to use my hammock about 113 nights. I currently use Dynaglide whoopie slings as part of my suspension system and wonder if I should have a second (or third?) set of slings, just in case mine give way. This is a long lead up to my question of longevity... I just don't have enough hang time to know how long my current gear will hold up. Any thoughts? If it matters, I am currently using a home made, gathered end hammock.
