WTT or Sell/tubular tires

Hello all,

I just purchased a tubular wheelset for cx and it came with road tires glued up. One is a vittoria evo corsa cx the other is a ritchey prologic both 23mm. They seem to be in great shape and the seller(another obra member!) said they were practically brand new. I would like to trade for something along the lines of an FMB,Dugast or Challenge. Basically cotton or polyester casing. I'm willing to trade straight up for a used/similar condition set or pay the difference for a new set you may have(would prefer the latter). Also willing to sell the tires I have currently.
Thanks
Sean
