ARDeerSlayer,First off,in my opinion,you can't go wrong with any Summit stand,but you did'nt state the reason way you wanted the backpacker model.I just replaced my old Viper with the new Viper X4,the improvements Summit made to an already great stand are outstanding.The only problems I'm having are #1,waiting for the hunting season to start,and #2,keeping my hunting buddies drool off the X4 when they look it over...Bob
