I am trying to decide between 2 camera backpacks. I like the idea of the pack because I will be doing a lot of walking on trails, etc with my camera. I will not be carrying much more than a camera and 2 lenses. So far it seems to be betweem to similar packs: Tamrac 5273 Expedition 3 Lowepro Micro Trekker 100 If anyone has any first hand experience with either of these and any likes/dislikes, I would be grateful for the comments. thanks again!
