Forever now I have used a 6' long x 3/4" tubular Nylon tree hugger w/loops sewn on each end with 6' whoopie slings. A few weeks back I was doing some bartacking so while I was at it I built myself some 6' long x 1" Polyester tree huggers with sewn loops on each end. These straps are basically the exact same besides the material.
I headed outside to give them a try and for some reason my hammock didn't feel as "comfortable" as normal. I readjusted everything several times and I just couldn't get it to feel right. It felt like I sank more in the hammock then normal and I just couldn't get "flat". So I traded the polyester tree straps out for my nylon ones and it felt great.
To make sure I wasn't crazy I had my brother do a blind hang test. I had him lay in the hammock using both setups and he could feel also feel a difference.
This got me thinking... Maybe its a mistake to use a Polyester tree strap with whoopie slings because the live load is not properly being transfered to the whole system and instead the load is directly on the hammock.
Has anyone else noticed this??? Are there any engineers that could explain whats happening?
