Picked this up from REI scratch and dent $50. I prefer it over the Arc'teryx Miura for the better organizational setup. I just took it out for a day packed w/ 60m rope, single-pitch trad and sport racks. + shoes, chalk, harness, lunch, 3 1L nalgenes, hydration bladder (in special pocket), personal effects (in special pocket) - sunglasses, wallet, keys, etc. Found that everything was EASY to access without dumping the contents of the pack. Also everything except helmet fit inside no problem. Plenty of room for everything you need for a day at the crag.
I found that the pack is a little short for my torso (I'm 5'11") - hip belt sits too high, so had to share some of the load on my shoulders. Even so, a 5 mile trek fully loaded was still a comfortable enough carry.
The beefy construction and many pockets adds some extra weight to this beast. I would not use as a substitute for regular backpack due to the boxy shape, lack of waterproof zippers, no top compartment. Strictly for climbing use. Also probably not great for peak assaults or mountaineering , etc. Included rope tarp is ok but rope management is easier to just throw in the 'ole rope bag if going to be moving from route to route.
