Think of it this way; when drive in your car, do you use a cup holder or a camel back for the beverages you enjoy there? Do you use a CB when you are on the computer, or watching TV?

Some people seem to feel they can't control a bike when reaching for bottles. OK they have to do whatthey have to do, but for the rest of us, why should we be the beast of burden when the bike is begging to do the work?

Water bottles are great for carrying a lot of water, drinking it fast, collecting from sources, cleaning up/maintenance. There just isn't any disadvantage. You can use both systems if you want to, but out from under the foliage, I sometimes need to cycle a lot more water than is practical in a CB.
