20feet up harness for me�lighter than the HSS, more comfortable, no annoying strap around my neck to get in my way when I'm trying to shoot or climbing/decending and also when I'm trying to pull my hood up on my head or when I don't want the strap acting like a wick soaking my backside when it rains, alot more versatile than the HSS style (can use it to hang from the tree with all arms and legs free when hanging a lock-on or rig it lineman's style, exponentially alot safer than any HSS style ever thought about being. I must mention though, that I am a former HSS user but I switched primarily because of the safety aspect and the versatility.
