My first FG/SS was a converted Atala Gran Prix. I built it up with a flip/flop hub, but found I never used the freewheel side.
Eventually I decided I needed a dedicated fixed gear bike, so I sold the Atala and built a fixed gear frame based on the geometry of my favorite road bike, but brought the bottom bracket up a bit for clearance. That's been my main fixed gear ride for years now.
