The Boss. Just plain too rough, and not good enough of a ride to make up for it. (Why, for example, is there a flat straight piece of track at the bottom of the first hill? I know some have tried to pass it off as a double down with a lengthy run between the two downhill portions...) Williams Grove Cyclone is very rough (especially the ending) but I would ride that again and again (and I have). Iron Wolf, very rough, but I've ridden that over and over again. But the Boss...no. Hurts. Not worth the hurt.
