Broomd I know Kevin T uses a modified ULA epic that can do some pretty decent loads. Not sure how far he's packing his loads out but most people can endure just about any pack at 100 pounds if it holds together for a few miles, when you start packing out 10 or more miles is when a pack designed to handle the weight really is worth the extra weight. But it seems to work alright for him, but at 4.5-5.5 pounds for a hunting pack the Stone Glacier, the Standard Timberlines and possibly these new bikini frames are worth a look to shave some weight I guess.
