I have owned an API, Loggy Bayou, summit, and a Lone wolf, all climbers, My conclusion.....I will never own another climber other than a summit. It is by far more comfortable than the others listed, maneuverable, functional, and durable. the lone wolf was a great stand, but it was a little troublesome to adjust the stand if you are up in a tree. I devised a system to adjust my platform with my summit if i don't get it tight enough to the tree.
