You might, perhaps oddly, find yourself in agreement with casey stoner, who was notably unimpressed with the 2006 non-sns michelins.
It is all speculation, but I rather thought honda were fairly neutral on the michelin thing having perhaps a longer view, and dani's defection was puig/repsol driven.
I don't attribute valentino's pre 2007 championships to sns tyres btw, I always took j4rno's and babelfish's point that the major contenders all had them, notwithstanding the seeming catch 22 element, in that to be a major contender you had to have sns tyres.
I continue to object to complaints about stoner having a tyre advantage in 2007 though. If he did, tough.
The number of Riders/Teams who had access to the SNS's remains a little bit of a mystery, the only thing I have to go on is Kropo stating that he knew of 4-5. A lot turned the opportunity down, like Colin, as they felt they couldn't ride them, or didn't want to take the risk.
Bridgestone did have the advantage in 2007, now this is obvious, and it is credit to them, with the aid of the supply reg also. Michelin's financial woes may or may not have contributed to their downfall even without the implementation of this reg, I believe though that if the reg was not implemented, Michelin would still have defeated Bridgestone again.
I'm a little nostalgic over the tyre war years, it would be very nice to see them back, instead of 'Here are three compounds' off you go.......Another supplier in the mix would at least throw up the possibility of possibility.....
