Coz,
Nothing really happened. Here in So Cal we have 3 other race organizations to choose from. The most expensive is NASA. To be honest they all offer the same service so it comes down to what track and what day i would like to race.
I find the other organizers to be more friendly and the other racers more willing to accept you into the "family". This feeling has been confirmed to me by some good friends that are in the race class for many years.
Another great example is my brothers experience with them regarding moving from hpde 2 to 3.
The first problem is that the instructor that signs you off to 3 is debreifing while hpde 2 is running, so he is not able to observe you.
Secondly, moving up hpde groups is all subjective and the instructors there all drive different cars and all drive different lines so to evaluate someone's line is not a good assessment. I know there are other subjective factors that go into there decision.
After running with all the different organzations I can say that not any one organization is best, it just comes down to personal preference or in my case what track I feel like racing at.
The joke of the whole thing is that my brother is in a S2000 and running 2 sec behind me and I am in hpde 3.
