I've been looking at the sling-style backpacks as a solution for holding more gear and being easier to carry. The Tamrac Evolution 9 has caught my eye. Does anyone have any thoughts this pack, pro or con? Or is there a different one you'd recommend? Whatever I get I'd like it to be larger sized so that it will hold more gear down the road, and so that it will fit me better (I'm a big guy!).
My current gear is a 40D w/ grip, 10-22mm, and 28-135mm, along with a tripod remote and the usual various other odds and ends. Upcoming purchases will likely be a 70-200mm f/2.8 and/or a 100-400mm, so I'd like those to fit in the bag as well. Tripod attachments are a great added bonus.
