Does anyone have any thoughts on these two packs? I am going to buy a new backpacking pack this summer and I can't decide which. 5 day trips is probably about the max that I will be going, and have considered all the factors such as capacity, weight, durability, price etc. I am just wondering if anyone has any nit-picky details that makes them prefer one over the other. Stuff that the websites won't tell you. Thanks!
