Wow, do you get tyre reps at track days in the states? We're lucky if we get someone there selling tyres who's got 150's in stock. We certainly don't get them at club races, Grip 'n Rip attend the DP races and sponsor F250.
You certainly aren't going to get someone here who has any idea about an NSR250 running Alpha10's, there's just one person in the UK racing that setup....me!

We did get a talk from a Dunlop technician at level 1 of the Califonia Superbike School, it was him who said start at 30 psi cold F&R so that's why I always say it.
