Bit of both. Anyone over say 5ft 10 could benefit from a slacker seat angle and longer stays - adds a bit more comfort in theory and gives you a more central CG. I think the current emphasis on super steep and short is pointless for anything excpet the tightest crits.

My frame is technically a 62cm, so the head tube is not 'extended' - the frame just looks smaller than a regular 62cm because I designed it that way The only tube oversize by modern steel standards is the seat tube which is a ø31.8 - most steel roadies have a ø28.6. The top tube is ø31.8, down tube ø35. The seat tube is the second highest loaded part for the frame ( second to the down tube ) - that's why I went bigger there.

48mm rake is pretty cool. Took a little to get used to, mainly because this is my first roadie in quite a few years, but I like the feel. The faster you go, the better it is...it's quite amazing. I was doing 85kmh down that hill between Gisborne and Melton, and it felt like I was standing still.

I quite like the wheels so far Nev. They're not super stiff, but stiffness ain't that important to me. So far no flats, and no truing needed after the initial settling in period. I wouldn't mind something else, but these things are light as sin and accellerate really well.
