I don't use a particular brush per certain types of wax, but definitely a different technique for the conditions you're going to be in. Course finish for wet days, and a very fine structure for azz cold days. As far as technique, I got my training years ago from a Swix/World cup tuner, so i'm fairly certain my stuff is pretty well on par with a 'pro' tune. I never stone grind either. I don't really use super expensive waxes anymore cause racing isn't a part of the equation.
Nordic Violet and a good brush and edge debur are pretty much all I use for keeping a fairly descent edge and base.
I'm confident that you won't beat me in a race based on tune.
It'll likely be caused by the fact that i'm of legal drinking age, and drinking and riding is just too much fun!!
