You've made the right choice if you're happy with them. Just as another data point I went with the Corsas as in my mind they're the things that are keeping you "attached" to the road/track. Plus I live in Ca so weather generally good all year round.I was advised for comforts sake to go for the normal PZeros due to the tram lining produced by Corsas. Have I done the right choice?
If I'd had a wider choice I would have gone Michelin PSC2's without thinking about it though and then the Dunlop Sportmax. Never been a huge fan of the P Zero to be honest.
