RE: Lone Wolf Sit/climb dissappointment!
Don't forget the Summit Bullet Backpacker.. it's basically a Viper X4 that folds flat. Very easy to use and setup.
Summit Viper
Summit Goliath (wider version of the Viper)
Another one that you might check out is the Ameristep Non Typical climber... it's a tad wider on the top section than the Summit Goliath.. and has alot of nice features for a good price ($219 at Gander Mtn)..
