If I had it to do over again I would get tubies hands down for road racing wheels. Right now I run Cosmic Carbone SL's and they are fine for FL but once you start going uphill, they feel like bricks. I picked up a tubie disk and just recently a tubie trispoke and there is nothing scary or hard about them. The only thing that sucks is how expensive the tires are (if you want to run quality stuff).
