Agree with GiantJ and others, make some changes and see how it goes.
I once built up a scandium framed bike. It was a thing of beauty, but I never felt comfortable riding it, as it was to light and I couldn't believe it wouldn't snap (all in the head obviously). I sold it and bought a secondhand airborne, after a few part changes (well everything bar the cranks and frame) I now think it's 'king awesome.
I do however have the luxury of 4 bikes and always have the right one for the kind of riding I do. hmmm, could do with a better road bike now I think about it
