I've had an aluminum Summit for years and love it. Most comfortable stand I've ever used. I'm a fan. BUT ... it isn't suited for every situation. In fact I only use it when hunting closed canopy timber where trees are tall, straight, and no low limbs. I find climbers all but useless in field edges, swampy areas, scrubby stream bottoms, gnarly regrowth around farms, etc. Climbers are the best choice where appropriate, and hang on stands are better in other spots.
That said, dont be shy of hunting from the ground. Seems all the focus these days is on being high up, whether it be ladder, climber, saddle, shooting house, or hang on. The ground doesn't get much attention but it can be every bit as effective as being high, especially for mobile hunting.
