For hammock suspension, I've been using a carabiner to connect my hammock's continuous loop to a daisy-chained tree-strap. This works, but I wanted a bit more flexibility when fine-tuning my hang. So, I purchased a pair of whoopie slings.

Looking at it now (and I probably didn't think this through), it just seems like an additional link in the chain. I've doubled the number of connections in my suspension.

Are there reasons for a whoopie sling over a cinch buckle or beetle other than weight?

Am I missing something?
