Harry, you can look in my Profile for the measurements of all of my current drillings. All Pins are under the RF or under the bridge.
Harry, I don't know who is drilling your balls, but it might be worth your time one day to come up to Edmond and see Anne Marie Duggan and see if she would watch you throw a few balls and make some drilling recommendations for you. If you did decide to do that sometime, call her pro shop before you come, to be sure she is in. I believe it is only a 20 minute or so drive from where you are at isn't it?
