The Roadini has been an eye opener for me in terms of seeing how Grant has evolved in his thinking. I really like the idea of slackening the head tube and making it up with increasing the rake. The result is a similar feeling geometry but no toe overlap and room for wider tires. I suspect if I ever end up getting a new custom frame I'd use the Roadini geometry, shorten the chainstays by about 1cm, and increase the BB drop to 82 or 85mm (don't ever pedal around corners or use tires less than 700x30 --- since I like and use clipless pedals I'll still have plenty of room), and it'll be pretty much ideal. I agree that you can't beat a low BB height for cornering and descending.
