I have a Summitt climber as well. Pros are mobility and comfort. Cons are you are limited to trees you can climb and hauling it around, even though it doesn't bother me at all.

My opinion, if you hunt several spots, a climber is ideal instead of several hang ons. If you always hunt a particular spot, get a hang on or ladder or two. I have a cheap hang at the spot I hunt on our land, due to terrain I really can't use my climber where I would like. Hope this helps, good luck.
