I guess I'm on the right track then. I got back on my geared bike yesterday and had to really force myself to coast and to shift. I think I only shifted twice. My pedal stroke is really smooth now, spinning up for a sprint feels excellent, and I now run the seat about 1/2" higher on all my bikes.
Nothing bad at all to say about riding fixed, though I do think it is slightly more dangerous, as it adds more opportunities for things to go wrong in emergency situations, and stopping and starting at red lights is a major PITA when I have to unclip (working on my trackstands to remedy that). I think with more practice I'll be as safe as I am on my geared bikes.
It's a fun way of finding out just how good your road frame really is. Puts the quality of your frame front and center, with no gears to hide behind. And the silent ride is to die for, no one ever hears me approaching from behind.
