I had a Centerforce but went to a Centerforce disk with a FRPP HD plate, odd combo but works well. I have had Spec Stage 1, Spec Stage 2, and a few others. I always liked the old FRPP King Cobra for the price. I looked up the mongoose and everyone that has one likes it, only bad comments were a little chatter on clutch brake in. Might be worth it for the price. If you have the $$ A Spec + series clutch is nice and like mentioned the Centerforce DF is a good clutch.
