I've just started using my LWHC to go up the tree and rappel down using 40" of Oplux. Kong Chuy and an auto block. I got everything from
@DanO Eastern Woods Oudoors. When I rappel down I just leave the LWHC on my feet just cocked so it doesn't grab the tree unless I want it to. I've got a Mad Rock Safeguard I'm going to use for climbing with the LWHC but haven't tried it yet.
