Hundreds of Bostonians can't be wrong. I think there are more flat bars than anything else around here(exaggeration but pretty dern close). The flat bar does work pretty well for exactly what you are describing inkd. I have them on my Pista and they are nice for the shorter rides. They do, however, cause a little pain in the shoulders on the longer rides. They aren't exactly intended for the agressive position you have while riding a track bike. Give it a try, you might like them better, especially if you don't use drops.

Right now on the Pista I am using regular bar tape but I have used Oury grips in the past. Both work fine by me. It might be a looks thing vs. a function thing for me but to others there probably is a noticeable difference in feel between cork and rubber.
