Mark,
you and the others are correct about transition response with the wide car tire... having said this, a narrower profile is much quicker than a wider profile. this was borne out at eureka springs when I rode the 205 darkside. I found this tire easily out handled my metzler 240 in every aspect. I know that many will say other wise and that's ok by me... just ask any one who's followed me during the rides. I'm sure they'll chime in and say for them selves.I'm thinking of a certian red/white classic with a dented tank that followed me and roni during a hard chase to catch the pack. He later repainted the bike with a really neat looking purple/raindrop and deep clear that was crazy to look at, his name is tony-mac... at any rate, what ever you decide to do, go with your gut, you'll be glad you did.
