That was a nice read

tigrrrtamer, I'd perhaps look into a Gios Compact frame. It has 74 deg ST and 39.5cm chain stays (with funky sliding dropouts... there is about 1cm of adjustement), a 26.6cm BB heigh (~7.8 drop). They don't specify the head angle but the fork has a 4.5cm offset, so I'd guess 74-73 deg for a 5-5.5 cm trail.

I just got a used 57cm one. Can't comment much on it since I did not ride it much yet, but I love it . I have tried other road bikes (a 54cm Marinoni and a 55cm Ryffranck), and can't honestly say I felt an obvious difference. But I'm rather inexperienced, i.e. don't ride enough, only in TO and Ontario, and usually quietly . It's the best fitting one so far though.
