I could do without bottles completely on most climbs, because I can't drink while panting. But then when I get to the top I'd really miss them, and I don't have a team car or domestiques to bring them to me. I could try drinking one bottle before the base of the climb, so I'm climbing with only one full bottle, but the total system weight would be the same.
