For those that remember the Roto Grip Gold Grenade, I was able to find one on eBay for $20 a few weeks back, in good condition. This is a pearl urethane ball with a core that is basically a lightbulb.

When I got the ball, it had already been drilled. I would guess you'd call it a label drill. The label is dead center in the palm and rightside-up (i.e., the word "Roto" is just under the bridge). The "star" is right below the words and if that little mark inside the "star" is the CG, it's dead center.

The span was very close to mine, so I just plugged and redrilled the thumbhole. I did not change the fingers.

Unless the pin was drilled out by one of the finger holes, there is no visible pin on this ball. There's something that looks like it MIGHT be a pin, but it is on the bottom of the ball 180 degrees around from the label.

The problem it's giving me is that it's trying to track right over the thumbhole. In fact, it's almost tracking like a full roller. My PAP is 4 over 3/8 up and the only time I hit any of my gripping holes is on my Girard-drilled Columbia Reaction Roll, which has the pin under the thumb, and I might only clip the thumbhole once. I don't even hear it.

But on this Gold Grenade, it's hitting the hole six or seven times, loudly, before it flares away (and we're talking about a ball with a max 1-2 inches of flare, so it's not going very far). In order not to hit the holes, I have to tilt the ball way over, and that's not why I bought this -- I bought it to play straight up the track when the track was dried out.

What can I do to fix this?
