Well, I have seen balls with 4 plug jobs on it which would still perform well, and I had a ball I used on 3rd drill - I did not expect much, but the ball turned out to be a great success.
Two things to mind about plugged balls: once the dynamics - any plugged hole will alter the ball's static weights through different densities, especially with deep holes that touch the core. Flare potential could be affected, too. Nevertheless, a pro shop should be able to determine the statics to find a proper setup.
Then there is the poetnatial problem of plug material in the track area. It does not offer much friction and my protrude from the surface if it is not even. This might affect ball traction and predictability, especially if you have several plugged holes in the track and you have resurfaced the ball after plugging (the plug material is normally harder than the coverstock's resin and does not sand away evenly).
