I agree with Bill. Think about national numbers in the ABA, Amatuer title, Cruiser title, Girls title, Pro and Pro Cruiser title. No novice or rookie in there. Even their NAG plates are by age not proficiency. The NBL is the only sanctioning body that I know of that has national numbers for Rookies and Novice. It gives the less skilled riders a reason to go to nationals and the grands, but no incentive to advance. I know this topic has been done to death, but I thought I would throw in my $.02 anyway.
