It is all relative.  Good golfers know their clubhead speed and the angles associated with their address.  But the average golfer has no idea.  The same can be said for other sports/activities.  Cyclists have cadences each tries to maintain with specific gearing.  Tennis players have specific string types and string tensions for different reasons.  When someone is ready to improve, they will learn more about their sport.  Beginners may not need the same type of information as the pros, but there becomes a time when it will be needed to get better.

I know my speed and PAP. My driller knows all my specs and I trust him to do me right when I get a ball drilled. Im sort of the opposite on how I think I look and how I actually look when throwing the ball. First video I saw of myself I was like holy S*&T I look like crap, who is that guy!!!! People who bowl with me in leauge, the wife and my driller (also coaches me) tell me otherwise. They seem to think im smooth, have good footwork and when I dont grab at the bottom my release is pretty good. Aperantley im really hard on myself and lack a bit in confidance and I still have no urge to see myself on video again.

Some people over think things.  If the driller see's you bowl then you shouldn't really need the details unless you are bowling sport shots (99% of bowlers don't ever).

To the OP, welcome to the most fun part of being a pro shop operator. 

KNOW YOUR GRIP SPECS, you be glad you did!!!  if you move from city to city or don't have a Driller that you can stay with for a long time and trust, it's a good idea to know IMO.

I wanted to learn about my specs..Because of my bad experiences with drillers.  I know my grip and all axis's in my head all because I put my trust on these "trusty" paper on the wall drillers and had bad fits. I used to work a lot with my hands and learned to "FEEL" different things I placed on my hand. It was part of the job. So early on, I knew how my hand felt in a good fitted ball and in a bad one.

In my old job, I moved a lot and had funky hours and days off. Finding a driller with hours that fit my schedule was the only way I can get a ball punched up.  I've had drillers who copied a ball, check my span, or took from a spec sheet I gave them, and still mess up my grip. Over the years I've had over a dozen drillers who worked on my equipment and I can only think of 4 who did a good job. (two are on here - thanks guys). And when I do find them, they leave lol. (Mike M., Rick L. - thanks man. Llyod and Kieth non BR members were the other two. I think Kieth is back on tour? not sure how true that is.)

I had to modify what I said about keith, I'm pretty sure he told me. but, that was a long time ago.
