I recently set my Kelty Redcloud 6600 aside and purchased the ULA Catalyst. I now have the Catalyst and really admire the quality of the pack...think I made a good move! My question to those of you that use the Catalyst or the Circuit...how do you load it? A fairly large percentage of the carrying capacity is "outside" the pack. I don't like using the camel water delivery system so maybe I'm at a disadvantage....the large hip mesh pockets don't seem best suited to carrying water. Do most load the mesh side pockets with stuff sacks...also the mesh pocket on the back of the pack. It does have 4 water bottle holsters on the front of the pack which should be adequate. Any inputs on what has worked for you would be greatly appreciated. For info...I carry a 2lb down bag and a Double Rainbow tarptent. Thanks and cheers.
