the treesaddle, no question about it for me. About 3 pounds and you shoot all the way around the tree, hide behind the tree trunk, wash it to keep it scent free. One will last you a lifetime. No noise, no one can steal it, because it is always with you. Takes a little practice to learn to use it and be comfortable, then you are all set. All sorts of step options: screw in, rope on, strap on ladders, tree spikes, tree branches, etc.
Everyone has preferences though. 20 bowhunters, 20 opinions....haha. At least we live in America and can use whatever we like.
