Light grinds are very under rated! I used to grind very harsh and my brake would be good, but for the past year ish i have only run light grinds and i have to say it is alot better! I am running coust pads on my koxx rim with a light grind and the brake is insane! Koxx yellows are good pads, deffinatly a light grind for them though as they can wear fast on harsher ones. Adam
