Thanks Juggernaut, I ran across that as well after I posted this thread.
I've put holes in it once and just wanted to be more careful the second time around if I do end up trying to redrill it.
These balls actually have 3 "pins", two for the top of the core and one for the bottom of the core. I somehow managed to lay it out so 2 of those pins are on my track, making for a ball that flares less than a 3-piece ball.
