Thanks, angrysparrow... the SRL is adjustable with a fixed closed loop on one end and the large adjustable loop on the other... I can attach the fixed loop directly to the Whoopie being used for suspension??? Or, should I attach it to the heavy cord that now has the carabiner previously used to attach to the webbing around the tree?? On the adj loop end, can I use a carabiner and attach to either the suspension Whoopie or the heavy cord?? My lack of knowledge is making my questions less than clear, I am afraid!!!
