The survey that went out was to people who were or are Major's competitors within the last two years which for some reason it seems many Major competitors did not receive. Thank you John for enabling me to complete mine.
There are many people on here who are Major competitors so not sure why you say the majority are regional only, I do see some as well but don't see it as a majority.
I am 99.9% sure this is not something that is only asked for by regional competitors. If I am wrong then I really missed the whole point of the many threads on here asking for a spec tire with multiple Major or National winners saying they agree to it.
