IMO there are no 'best'RFTs yet. My current S001 19"Potenzas staggered(style 401) are sporty and precise but also NOISY and harsh.
I just ordered a style 398 18 inch RFT Continental winterset with the 225 square setup at my dealer.
But next spring I'm going to get rid of the Potenzas S001 rightaway and order NON RFT 19"Michelin Supersport summertyres in the same 225f 255r size. The NON RFT set comes with a spraycontainer to 'repair' punctures so you don't need a spare tyre.
