Resupply w/additional water?!? Where's the helo? Where's the water buffalo?

You make a good point. And while I prefer the HS to the C, I can think of a couple of courses I took in which I was carrying both a Camelbak and two to five quarts of water in canteens. I think the answer is, as always, "it depends." Depends on what you like, what you need, and what you are doing. . . .
