And why would the driller provide it for you to do that? Last I checked pro shop owners didn't charge a separate fee for fitting. If they start charging for fitting like an eye exam, then you have the right to the info. If it's part of a ball purchase they aren't obligated to give it to you, even if it is your hand. They may choose to give it away, but I see no value in that for the pro shop, only the e-tailer.
It's also going to ruin any relationship you could have with your driller, if you bring a ball to already drilled that needs substantial adjustments. The last thing I want to do is work out a ball that doesn't fit and has never been down the lane.
Doing business with any retailer is a two way street. So many online purchases are wrong for the customer. The OP is looking at premium balls online when he needs a Groove, Tornado, etc. A visit to a good pro shop would have set him in the right direction instead of being told what to get by strangers on a message board.
As a ball driller, I don't want to work off another's measurements anyway. Way too many shops use a non standardized system that can be confusing to a shop using a different system. I'd much rather match a ball than take responsibility for the supplied measurements being correct.
