No bladders, hoses, etc. Still use two Nalgene quart widemouth bottles (the translucent, not the Lexan). MYOG pack has a sleeve on each side about half way up into which each bottle fits snugly. Stiffeners sewn in at top so bottle goes in easily. Easy to clean. Easy to carry from the water source with cap retainer looped over a finger. They last around ten years, but I replace them before that. My loaded pack weighs around 20#, so taking it off to have a drink is no big deal.
Another one: Leave the GPS at home. Use a swiss DP-6 Box compass and either Trails Illustrated map, or scanned portions of NGS Quads on both sides with new trails and routes drawn in and then laminated between the thinnest plastic laminating sheets could find. At my age, decided carrying a McMurdo PLB had to be a must, so something else in the gizmo dept. had to go. Sometimes even leave the camera out (gasp), and still have just as much fun.
