I purchased a Summit treestand three years ago as my first climber and immediately returned it: I could not imagine lugging that bulky stand through the woods. I then purchased a Lone Wolf Alpha: while I loved the compactness and light weight of the Alpha (and also liked the built in bow-holder), I found it much too difficult for climbing and extremely uncomfortable for sitting.

The following year I purchased the Sit 'N Climb seat portion to go with the the Alpha platform I already had (an additional $140). I have been very well-pleased with the Sit 'N Climb stand: it folds into a compact package, is still lighter than most other stands, climbs easily, is very solid when attached to the tree (the two straps that secure the seat assembly to the platform when set up in a tree help make the stand very solid), and is sufficiently comfortable for the 3-4 hour sessions that I hunt. I only wish that I had spent the additional $40 initially to get the Sit 'N Climb.

That being said, I can certainly see reasons to prefer the Summits: either because of the exhorbitant price increases for the Lone Wolf stands in the last year or because of a premium on comfort. The Summit was a very good stand, but I have found the Lone Wolf to be much better for my needs: I am glad that I have it and have no plans to change.
