I have a older pair of climbing stick that I have been sitting on for a few years. I don't know who made them by they are older steel stick. I am thinking of getting them out to use for spring hunting and for next fall as well. The thing about them is that when you attached then to a tree you have an 1/2" rope that goes around the tree then has a cleat that you would half hitch the rope onto. is there a way to convert these to a more modern clinch strap system? Or should I just used the rope and not worry about it?
