I have a lonewolf sit and climb. I have yet to use it as a sit and climb. I use it just like a hand climber and slide the bar up under while climbing.
It is without a doubt my favorite stand I have ever touched by butt to. It packs great, weight is great, climbs great, and is the quietest stand i've ever used or heard of.
The only problem I've seen with some larger trees(not "huge" ones) that the LW isn't very wide. Even if it fits around the tree, if its close to the max diameter, it'll have be slightly harder to start climbing with, but that is usually only a couple steps up the tree.
