Same problem.

I tried the camelback and don't like it.

I bought this stem mount for a water bottle and it works perfect: http://www.cambriabike.com/King-Cage...Cage-Mount.asp



But, you can't easily flip your bike over to change a tire.

For another bike I found another type of water bottle mount that goes off of the handlebar. For the life of me I can't remember who makes it and I can't find a link. Maybe tomorrow in the daylight I will look at the holder and see if there is a brand name on it. I like it. It doesn't interfere with flipping the bike over and it is really stable too.

I did not go for the cage off the rear because I have carbon rails on my seat and a carbon seat post. In restrospect, that might not have mattered as much as I thought.
