I love my Camelbak. I haven't used a wter bottle in years. Never have had problems with sloshing or overheating. I have noticed though that I used to see more Camelbaks a few years ago than I do now, like they are becoming less popular. As for me, I don't get it. If they ever quit making them I'm going to buy enough to hold me til I can't ride any more.
krispistoferson: The wine idea doesn't sound too bad. A nice White Zinfandel, some cheese and a shady tree would be a great mid-ride break.
