I have a Mean Machine drilled 2 7/8 x 4 3/4 with the MB on the VAL and an X-hole 1/4" below the PAP, which is not giving me the strong backend I was looking for.  Since I want it to have a stronger backend than it has now, I'm thinking about having it plugged and redrilled in order to change the MB location from on the VAL to where it's in the strong position right of the thumb hole.  It seems to me that by doing this, the old thumb hole will wind up being in the track area.  Will this cause any problems?  Will this give me the strong backend I'm looking for?

Also, maybe as an alternative to plugging and redrilling the whole ball, would I get a much stronger backend by just having the X-hole on the PAP plugged and redrilled 2 1/4 - 3 3/8" lower on the VAL?  If it does, would this be a better way to go than redrilling the whole ball?

Based on what I've seen from Nick and Brunswick, moving the weight hole won't have a huge impact on the ball's movement.  If I had to put a number on it, the weight hole makes up 2-5% of the ball's reaction.  Putting a plug in your track won't make any real difference if done by a quality proshop (no humps or flat spots).  True a portion of what the ball is rolling over will be a different material, but I have several honor scores with balls that have plugs in their tracks.  I'd try adjusting the cover first.  If that doesn't work I'd personally plug and redrill.  Maybe one of the Track experts like Clint Daley will respond.

I wouldnt put a plug in the track if the ball flared over it on the backend.
