Felt DA water bottle Help

Taken possession of and love my new felt DA. Not only is it fast, but it is an aerodynamic thing of beauty. So much so that I hate to even consider putting a water bottle on it. Looking for recs on the best position as aero does not overcome dehydration. Looking for comments on seat tube, Xlab carbon wing, Beaker Concepts Hydrotail? I will race long course with a profile aero handlebar mount. I know this has been hashed to death, but I didn’t mind the x-lab on my Look 486. It just doesn’t seem right on my Felt.

I’ve contemplated starting my own IV and loading a liter of LR prior to each ride just to keep the Felt clean. (kidding)

i just got mine about a month ago. Went with the Hydrotail. Seems to work good so far.
