I intend to get a 2nd hand ball(owned by a right hander, i'm a lefty), but it seems that the previous plugging is somehow in my track line(I'm a high tracker), does it affect the ball's reaction if I use it ?

it does not affect at all usually..you are lucky buying a right handers ball and being able to redrill it lefty because you have a brand new track to work with.

Yes plugging does affect a bowling ball, you have to think the when you drill a ball you drill in to the core changing the dynaics of it. Plug is only 1 density so when you plug a ball you will again change the dynamics because bowling ball have 3 diferrent densities: core=high density, filler=low density, cover= medium density. Most people wont notice the difference but I don't recomend buying a plugged asymetric ball unless your driller has a Morich Determinator, because once you drill into an asymetric ball the mass bias actually moves from the marked spot on the ball. The determinator can locate the mass bias by spining the ball till it the ball rotates around the Prefered spin axis/mass bias and then mark the true location of it.

Other than that just try and try to make sure the plug is out of your track.

I don't think plugging affects the ball's reaction as long as the plugwork is done correctly and not in the track area. Almost all of my arsenal has some plugwork and when laying the ball out my driller will usually avoid putting the plugwork directly in the track area if possible. As far as drilling into the core and changing the dynamics of the ball, who knows? Mo Pinel maybe? Might make a difference for a touring pro, but for the average Joe I would bet not...
