Archinutt-

My speed and distances are almost identical to yours. 2 months ago, I bought a Novara flat-bar road bike at REI (last year's model) on clearance for $750. It's pretty well outfitted (Shimano 105, Mavic wheels, etc.) and I really like it, BUT if I did it all over again, I would get a drop-bar bike. The winds here in the Dallas area are seemingly always around 20 mph, and I am now presenting an even bigger wind drag since I'm more upright. Plus, I didn't think this would happen, but I definitely have a "need for speed". Only been back on a bike for a couple of months, but am already wanting to keep up with the skinny guys (I'm 6'4" - 260). Just my $.02.
