It's awesome and great to learn from the testing that you guys did on the track! I've been a pure TT cyclist for the last 4 years and been on a few different TT bikes from a P2 to a P2SL to a BMC TM02. I recently bought a small Trek Speed Concept 7.2 and running a Hed Jet 4 in front and a Hed Jet Disc out back, with a Bell Javelin, Castelli short sleeved aero jersey and an Elite Chrono aero bottle on the seat tube. Pretty fast setup for the rolling hills here in the San Francisco peninsula.
How do you think a round bottle behind the seat neatly tucked away and pointing straight back would perform? Given that most of my rides are fairly short between 20-30 miles, having one bottle is all I need. I've tried all sorts of bottle placements with round and aero bottles, but still trying to decide which has the least drag penalty while having ease of access. If the bottle behind the seat is much better than my aero bottle on the seat tube, then I'd be inclined to switch over despite it being hard to reach. I know it's very personalized on position as I've read but if you have any general insights, I'd appreciate it!
