Your statement is true . . Activator does get through the heads better, but revs up in the mids and is smoother on the backend. PK18 wants to start hooking earlier, and whenever it does start hooking, it's sharper. I wouldn't say that one is necessarily stronger than the other, they just allow for different reaction shapes. Let's just say that PK18 LOOKS more aggressive at least.
