I'm replacing my Havoc SC Pro system (Ballistic 550 4.5) with the MMP and pro4 4000. I'll have all pinons 12-15 to try out.
I've noticed that no one really seems to run smaller suprs than the 62, is there a reason for this? I was going to try 13/60 on the 4.5t but motor crapped out before I could try it.
