Erin "THE ROCKET" Peterson won the "F" stock class at Princeton this year on a 75 400 whip. 2nd place was a 73 400 ccw, 3rd and 4th were 74 super stingers. None of the mercs or yamahammers made the final. I think she also won a class at Eagle River also. But, most of the time she's chasing the super stingers.
