add me to this long list vouching for the Bontragers. i rode them through philly almost daily for a year, including the glass covered roads outside of center city and haven't had a flat yet. only occasional skidding/skipping so not much wear from that, and they feel nice.

they also come in a few colors.

but they make a happy zippy noise when you skid :)

i got a pair of fortezza SEs for $25 a pop at performance and have been running them for a month with no problems. they roll faster than the conti ultrasports that came with my pista. the ride is smooth, and i like the 140psi. it's not a good ride until you feel it in your bones. i'll never buy contis though. those things made me feel like the bike was going to fall out from under me in a hard corner. not so with the fortezzas. they're grippy! i think when my new wheelset gets here though i'm going to get me some Vittorias, forget what model, but someone mentioned them to me on this forum sometime or other...
