I've got 2.

Viper: Love it. Most comfortable stand I've seen. Packs just fine....and I can be up and hunting in about 5 minutes......quietly.

Bullet Backpacker: Same as the Viper...except it folds flat for packing. Useless attribute IMO. I've never broken it down to pack it flat.

Both great stands.

I utilize a climber about 45 times per season.
