Thanks Carl.
The Dura-Ace kit looks great on the Banana frame and the bike does almost look brand new (a few scratches here and there if you know where to look), but because everything is used, it means I don't have the usual nagging doubt in my head that I normally get when I build a bike with NOS kit... to ride it or not to ride it... this one is definately a rider.
Like you, I've built a few bikes over the winter and now have 3 or 4 to choose from when the weather decides to sort itself out!
