As I'm learning, it can be quite tall without being a visual problem. When I built the frame, Doug Fattic said, "I want you to still be able to ride the bike in ten years" (or words to that effect). Accordingly, it has a small extension (~10mm) on the head tube lug, and the steerer tube is a bit long, necessitating some spacers (a plain spacer and a Paul Funky Monkey). After I go to my eternal reward, the next custodian of the bike can cut things down if they want.
