Whatever floats your boat

Back on topic, I wonder if the "heavy duty" PP that Spec has makes it a tad more harsh? Do all the different stages of Spec use the same PP, or are they stage specific?
My guess: the higher the stage from Spec, the "harsher" it'll get. But from what the stage II and III owners have said, it sounds like the chatters begin to go away with break in time and actually getting used to their new clutch.
