I have never gotten hip or shoulder strap bottle systems to work for me. They get in the way and are just a plain pain in the you-know-what. Also, I have never really had a pack that was convenient to reach back to grab a bottle. My old Circuit was an exception, with the slanted pockets, but a Platy would not stay put... they fell out and forced me to use water bottles, not a major compromise. I tend to stop and drink, I like that method best. But I probably do not drink as much water as most people, being desert acclimated.
