My highest speed crash ever was from hitting wet grass at about 70 mph running trials tires. Just the slightest touch of the front brake to set up for a turn and I was instantly on my face sliding. I may as well have been riding on ice. I am almost convinced to try a rear again on my 200. But I don't think I will ever have the guts to run a trials tire on the front again. Just the idea of going down a steep hill or hitting slick mud on a front trials tire makes me cringe.
