In reply to chris fox:
I have had Rubino somethings with Kevlar on my hack bike for years - I've only ever had 1 puncture and that was a snake bite from an abysmal attempt at hopping up a curb.
Commuter has a set of Gomme Italia things on it that came out a box of random bits I picked up - only had 1, maybe 2 punctures in them, although there are a few cuts in the tread.
The back one is pretty squared off now, so when they give in I will replace them with the Panaracer Extreme Dura ones that actually came with the bike, if they haven't perished by now.
Make sure you keep them pumped up pretty hard.
