thought I would help you out I bought the summitt backpacker, I hate it and am going to try to take it back because I am just not happy W/ the folding down part of it and packing flat part just makes ride from your head all the way to the back of your kneee, it is comfortable and easy to climb once set up but it also noisy to set up and take down. The folding down and unfolding also takes time. This model is also more expensive 250. I would much rather have the bushmaster x4 and am going to try to exchange it @ bass pro has anyone had any experience w/ this, will they exchange on the basis of non satisfaction.
