I have a good number of stands of quite a few types (in the mid 20's now) usually hang 'em all during the season. #1 stand, in my opinion, for a "hang and leave" is the Climax chain-on. #1 for a "hang and hunt" is the Windwalker. I don't know where to get Climax stands from right now, but I'm sure someone on here does, as for Windwalkers, the Bison Gear pack guys sell them. Climax stands are the berries - hang on any tree (slant don't matter), I've hunted trees down to 5 inches or so diameter (South Texas mesquite) up to 5 ft of extra chain types (Midwest oaks) - quiet, stable, comfortable - just a bit too heavy/noisy with the chain for a "hang and hunt" IMO.
Course I'm kind of biased for hang-on stands....I wouldn't use a self-climber if they gave me one - too constraining for the way I hunt.
