I just got a Summit Copperhead X5 that I am going to try in one of my favorite spots this season, I haven't hung it yet but just sitting on the ground it's very comfy and fits well. (I'm 6'3")
for sticks it's tough to get more versatile than Summit's Bucksteps. Where you need a pretty straight tree with an unobstructed sight line to your stand using a straight stick, the Bucksteps allow you to snake around branches in any direction you like.
I single climbing stick is quicker to set-up but the Bucksteps give you more options for tree selection.
