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.
I think they are trying to keep a "trade secret"... LOL If you are curious about it's geometry, you can do as I did, and order an inexpensive inclinometer on ebay. I'll be measuring my rides soon. Also ordered a scale...
But from the looks of the pictures on the link you gave, it seems like the head tube angle is rather slack. Looks like a stage race or bad-roads bike. May be a time trial bike... steeper seat tube angle, slack head tube for a more stable straight line ride (shortens the distance going from point A to point B).
