Stay with michelin. I had Pro4 for ages, commuted in the worst possible weather and only had 1 puncture with some metal debris that destroyed the tyre. Felt almost as fast as a race tyre, but lasted ages. Best tyre ever
They've been a favourite of mine for years but I'm a sucker for trying different things so I'll probably still grab some of the Pirelli just to burn through a set. I'd love it if Michi did 32mm version of the Pro4Endurance.
Tubes or TL? They sound nice on paper so I might keep an eye out for a cheap pair to add to my ever-growing tyre collection.
