Still haven't decided how I want to drill this thing yet. I'll be drilling it myself (just started that) and I want to do it right the first time.
Anyway, just as an observation, I've now seen about a dozen of these balls in person and no two look anything alike. Mine is purple, navy and just a little bit of orange. No yellow. There's some kind of Exorcist-pea-soup green swirl around some of the red, too. Still, it's a neat looking piece.
I'm going to try to drill it in a way that I can get some length, but not so long as to kill the reaction. I just don't need it hooking at my feet or anything close to it. I want it to get down the lane, and when it starts going, I want it to be a fairly predictable -- but deliberate -- move left. No skid/snap.
