Finally jumped on the bike and had a very brief ride just to check my work. Dave's description feels right: It's a real race bike, and the most natural position is forward and low over the bars, where lots of power can be generated. It's very responsive but it doesn't feel unstable. For me the fit is good and the handling nimble but predictable.

I highly recommend that any bike's alignment be checked and corrected if needed. Peugeots were built straight in my experience, but past accidents are to be assumed, and even a slightly twisted frame can really influence the ride. Thanks to Ed Litton for his work.
