OK I believe I'm sold on the Lone Wolf though I don't like the idea of the "sit and climb" model. I've been looking at some stands online and there is an

Alpha hand climber treestand for $329 and an Alpha hand climber combo for $307

Now I have 2 questions,

1) what else is different about the more expensive one other than you get a sit and climb strap whereas with the combo you don't?

2) is it just that pictures are deceiving or is the "combo's" seat thinner in profile?
