I had a couple when they first came out back in the mid 90's. Drilled one up leverage and the other with the pin over the fingers, straight over the label.
The cover was PK 17 and it was one of the last PK17 Zones before the original Danger Zone came out. At that time, I dulled the leverage one and kept the other highly polished for a nice one-two punch. Back then, the Sapphire was one of the stronger balls on the market and highly popular.
From what I understand, the Big B will mass produce some of there classic balls like the Sapphire if a large enough order is placed.
If you drill one, I would be interested to hear how it fits in todays equipment spectrum.
