As for mods to summit's, I don't know about anybody else, but I can't stand those elastic heel straps that you have to fuss with to get behind the heel of your boots. It's especially annoying with a big set of pacs. So I just cut those elastic heel straps off, left the green straps in place, and I use a 12" or so bungy cord. I just reach down with the bungy cord behind my ankles, and hook each hook onto the green straps on the outside of my boots. It holds a lot tighter than their elastic cords, and allows more control of the stand on the way up the tree, not to mention it's quieter, the tighter hold means no drag on the tree.
