I was about to suggest the Soloist Team. It's a great bike - road-capable and certainly quite aerodynamic. Ride quality rivals/surpasses that of many carbon frames.

When you test ride, see if you can also do some test riding w/ a pair of clip-on aero bars. Shops may or may not let you because clip-ons will slightly scuff the bar clamp area, but IMO this would be a very useful way for you to get a feel for the tri position. The difference between the tri/road position is that you sit further forward on the seat for tri (usually by moving your seat fw. or using a "zero-setback" seatpost) and the top tube of the bike should be slightly shorter so that you can get proper extension w/ aero bars. Talk about it w/ your shop.

Good luck!
