I have been researching packs and have narrowed down my top choices to the Exo Mountain 5500 pack. The top contenders were the MR Marshall and Metcalf and the Stone Glacier 6200 and 6900. I am interested to hear from those that have used the Exo 5500 and the other packs listed above to help determine if I am making the correct decision from my research. I would prefer a US made pack, outside pockets for a spotter and possibly a small tripod, and for the main pouch zipper to be on the outside edges of the pack vs down the middle of it. Any experience with this pack or others that I should be considering is appreciated. Thank you
