A friend of mine has been dominating the class I run for years , Sportsman (11.50 -19.99 ) resulting in multiple track championships and a Bracket Finals win resulting in a trip Pomona ,he has a fast car 11.50 at over 120 mph, he counts on his opponents being intimidated and going red so he can back off on the tree a little. Well since Tru-Start he isn't as dominant and has to concentrate on the tree more since he doesn't know if his opponent went red. He lost his edge resulting in himself red lighting and since Tru- Start hasn't won a class championship or done well at the Bracket Finals. I myself have a fast car in the class Tru-Start took some getting used to but I am okay with it.
