Thanks. I agree on the forks, they are just temporary stock forks snapped quiet cheap. I like them though. In fact I've recently put White Brothers SC70 from same year and they goes with frame rather nice. I'll update photos when I'll get chance to do so.
As for Dura-Ace, few reasons why: its shiny, its light, has super short cage which I like a lot, insane slick shift with dura-ace cassette (close ratio 11-23 is so sweet plus weight of only 160 gram)
The main idea behind this was to achieve kind of "micro drive" and it works for me very well.
