J - Your bike is one of my favorite conversions I've seen on here. I wouldn't change a thing.

As for my "should I" question. I have a friend who bought a Zipp 1150 for really cheap from an ex-racer on craigslist. He has used it a little on his road bike but since it's tubular and he doesn't want to mess with it if he gets a flat, he doesn't use it much and is thinking about getting rid of it. If I can get the wheel and tire for less than $100, should I? It has fixed and free sides and the fixed hasn't been used. Worth it for a toy or something to use at the track this summer?
