I know the 90 classes can be boring to watch but it is fun to leave on a pro tree. I run S/ST and don't run a delay box or a throttle stop. I slow my car down with weight and timing. So it kinda freaks some guys out when I take off will the wheels in the air and it lokks like I'm running all out. I usually run 10.90 125 mph.
I'm running A/S this year and to be honest S/ST is more fun to do. No matter what, I think heads up is fun and I've run alot of super pro and Pro bracket racing over the years.
