Very cool, nice to here your happy with your pista, I did notice the geometry, 75 degrees on both seat and head. I probably could have went with either 57 or 59, but I rode a 59 and it felt right, I'm 6'1" with a 34" inseam and long arms, I think I'll be happy with my choice.
As for the Bridgestone, I went down and looked it over closer, your right, it has semi-vertical drops, looks like I'll have to pick another victim for a project, an old 23" road bike would make a nice winter steed.
