I am getting a ball drilled up for my teamate and he is a full roller.  He has a full roller layout on his ebonite xcel pearl and it doesn't seem to react well.  It rolls out early and deflects off the head pin.  I was wondering what a pin up drilling would do for him on a new ball.  I would like to see the ball retain more energy for the backend and cover more boards than what he's seeing now.  I was thinking about drilling him up an action with a pin up leverage drill to see what that would do.  Does anybody have any expertise in this scenario?

The reason balls are laid out differently for full rollers than three quarter rollers is so the flare will reverse for the full roller and the track will not flare into the thumb and finger holes.  With any layout that does not reverse the flare in the grip area, a full roller will thump (if the ball has a dynamic core).  --  JohnP
