I can't speak about track performace, but if you do get the Pista Concept, you shouldn't have to worry about getting "street" wheels. The Mavic Ellipse are bullet proof. I'm by all accounts a BIG buy and I commuted on those wheels on the streets of Baltimore for 6 months without having to true them once before I sold the bike. The previous owner used that bike as his only transportation for 6 months before I got it. He never had to true them either. The only maintenance we had to do between the two owners was clean and repack the Sugino 75 BB.
Also, there were 3 of us that rode that bike around town.
Good luck with your decision.
