I bought a used act clutch that had 500 miles on it. I do not know how he broke it in but the disc looks alright to me. It has the performance street disc in there now. I was wondering if I should buy a 6 puck instead. I am cammed right now and upgraded to a .50 trim soon. Which one should I buy?

 

Any one have a suggestion? I need to decide fast because the clutch goes in next week. Either ACT extreme disc (which was used for 500 miles) or 6 puck.
