Don't forget about the $300 AMA license. And if the front runners don't like your line, you will become their berm. Pro racing IS a contact sport. There is only so much room, and the bikes move around a lot.
Weeded and Tez went faster in the spring too, but when the AMA time came up, it was a real struggle.
Again, it's better to get it figured out first, then do it.
I've been there, I can only give advice and thoughts....
