This is exacerbated when the tree is too big, which negates the tree diameter pro. The overall height of the expanded stands, combined with the stiffer braided cable design (vs xop's flexible, silicone strap) of the summit makes it annoyingly difficult trying to get it around a tree. The xop/lone wolfs fold completely flat, where as the summits are stuck up. The packability with the summit stand is also a huge factor. It's loud, it's bulky, the platform is smaller and the grates are spaced out too far for me to feel 100 percent saf. My wife mainly uses the summit and she hates it. The tree size isn't a big deal and although the xop/lone wolf stand is uncomfortable, I have had many all day sits in it.
The xop wins in everything besides comfort and tree diameter. I have a summit (specialist) and an xop (lonewolf hand climber clone).
