This is a topic that could go on for weeks with no right answer. Pros here pros there, when the real topic is your riding style.. I'm an am rider so not bashing am riders but why not make alllll am riders race Sunday this is where most of the track damage occurs ( locking brakes downhill , and corners, chopping the throttle out of corners , and up hill etc.) it's the riding technic that hurts the track. I've learned over last four seasons to ride more than that center 6 inches of trail and has made all the difference in the world. And I've always had Sunday races with the pros moved all around, but until I changed my bad riding habits it was horrible, now it's not much different than running on Saturday. It's technic not time, that's all I got..
