I use two climbers, Summit Viper and Lone Wolf (hand climber). The Summit is light, easy to set up, and comfortable. The Lone Wolf is lighter, not as comfortable, but the big plus to it is how compact it folds down to. Almost everywhere I hunt is either up or down a mountain side. The Summit's cables catch on limbs and mountain sides, especially when walking down a steep slope. Because of how much easier it is to carry, especially over rough stuff, the Lone Wolf is about all I use now.
