I'm reconfiguring my ring suspension system by replacing the webbing loops at the ends of my hammock with 6mm prusik cord from strapworks. To these loops I'll be attaching my rings. The cord is rated at 6000 lbs. I'm also replacing my straps that attach to the tree with Strapworks webbing rated at 3500 lbs. To tie the prusik cord loop at each end of the hammock I was going to use a double fisherman's knot. Does that meet the approval of my more learned colleagues? I suppose I should add, this is being attached to a Claytor Jungle hammock.

Thanks, Miguel
