I would search out a LBS that would let you rent both a performance hybrid and a road bike, keep them each for a day or two and see which fits the type of riding you expect to do. Maybe they would apply part of the rental cost towards the purchase of your new bike.

I have both a hybrid and a road bike, at the average speed I ride at, 19-21 mph, I am not any slower on the hybrid. That is over a 36 mile loop.

Since I am dealing with carpel tunnel issues in both hands, the bars make no difference for me, my hands go numb with either.
