I've had lots of gear that was useless. My large alice pack is among them. Too small to hold enough gear, yet the back of sits three feet from the small of your back making hiking absolutely miserable, if not dangerous because the weight pulls you backwards when turning, running, crawling etc.
When worn with your fighting load its basically impossible. The military wants a fighting load around your waist, held up with a pair of suspenders. Then your supposed to wear a pack that has a kidney pad and belt over that. Unfortunately you already got your canteens resting on your hips so the kidney pad has to rest on top of that which grinds the alice clips into your skin and the pad is six inches off of where its supposed to fit. For eight years I never figured out a way to make that goofy system work.
Furthermore, I never had a quick release that ever held. They use a plistic clip going througha metal wire held together by a little snap. How in the world thats supposed to hold thirty pounds is beyod me.
Now I carry a modified CFP 90. With all the side pouches cut off the pack fits the contortions of my body. Usually when hiking with it I hardly know its their.
I cut off all the quick releases and added some black hawk plastic buckles. They disengage even faster than the quick releases and so far will hold at a hundred pounds. I've yet to force them beyond that.
