To try to eliminate the influence of the core I would put the Pin 6 3/4 away from the PAP.
To eliminate the hook or change of direction totally, throw the ball with zero axis rotation.
The cover is the part touching the lane, the only friction point, least friction is plastic, zero axis rotation even with friction still not going to change direction.
So to answer your question, I'll suggest Pin on track.....but I don't think just that will do what you want.
