I have a SonicX that was drilled to go go to long not happy with that drilling I thought I woud get more back end. 5 x 4 1/2. I took it to the pro shop and told him that I was think of redrilling so I can get nore backend. he said that redrilling bowling ball is not a good idea it would not react the same. I never heard of that. I thought it did not make a difference if a bowling ball was plugged and redrilled. I'm I right or wrong.

Hi omega -

It is true that the more you plug and re-drill a ball, the more of its original characteristics will be lost.  The reason?  Because you are drilling more and more of the surface and core out of a ball and replacing it with plug - which obviously is not going to 100% identical to what was in you ball originally.

That being said, if this is a brand new ball and this is your first plug/redrill to it, I can't imagine that it would affect the ball that much.  You should be able to plug/redrill once without affecting the characteristics that much.
