So I am learning how to make whoopie slings from amsteel and I was looking at the suspension that REI uses for their hammocks and noticed that they have two buries in the sling. I've noticed that all other slings like the ones Dutch sells has one burry. Do you have any thinking for why REI would put two burries in their sling, besides the obvious one of more friction in the sling? It seems like a lot of additional weight when one burry has been shown to work just fine.

Thanks for your thoughts!
