If you haven't already, check out
http://www.rokslide.comYou will find lots of pack information, reviews, opinions, etc. I went through the search process last year for a new pack and it can become mind boggling. I didn't see anything but good comments on EXO but I went with a Kifaru. So far I have no complaints. Yes a good pack is pricey but when hauling heavy gear or meat in the mountains the price is forgotten but the quality in design and materials stands out.
Good luck in your search.
