i used to try all one rope, then i went to two ropes then i thought one day what the hell, try climbing with it and im back to one rope. only thing i pull up is the bowIve been climbing with my climber wearing my backpack for awhile. I dont see any problems with it. I only pull up my bow with my hoist rope. I had the hoist rope clip break loose before from too much weight and down went my bow.
Its safer to climb wearing it than carrying it in your hand....I can't see why it would be over 20 lbs for just sitting on a stand...
