Or can you get away with training/riding streets with your fixed/singlespeed all the time?

Right now I have a dilemma; I want to race track, I want to ride track, but I'm currently obsessed with building a road bike with Dura-Ace 7400 parts I have collected over the years (just got the pedals yesterday!) but I'm having second thoughts. I can't build both bikes...Well actually I can but it would cost a lot of money.

So, I was thinking of grabbing a Euro-Asia "Godzilla" frame (their upgraded bareknuckle made in Japan that is better made with better materials). I can still use my Dura-Ace parts (crank, pedal, stem, post and I'll get hubs).

Any opinions?
