I have owned F1's on other cars and been totally happy, and the F1A's have not disappointed yet.
It is very hard to compare worn out tires with new so i will try to be as subjective as possible.
The dry performance is great, good feedback and plenty of grip. On good tarmac and a hot day in Cornwall scratching round the country lanes i have been totally impressed but just how grippy the front end is. The sidewall is harder than i was used to, but no bad thing. The road noise is more than the SO3's they replace, but not deafening.
I have not been in wet conditions yet to give a detailed report, nor can i gauge wear.
