I just picked up the Eberlestock Stalker and it looks like it is excellent in quality and function, holds all of my hunting stuff, including everything that I will wear during the hunt so I know it will be perfect once I add food and water.
I have not yet used it out in the field, but can report back on Monday 
I am really liking this backpack, it has lots of room and fits really snuggly to my back. I tend to carry a little to much weight (for some people's liking) and once all the straps were tightened up the weight was dispersed and the padding held up so that it did not feel heavy at all.
