There's a lot that goes into choosing a bowling ball, and one of the most important, as far as getting the right layout, is the positive axis point. However, this is not specific to any one bowling ball. But it is specific to you.
The first thing you need to understand about the positive axis point (PAP) is it's different for every bowler. You can't simply look at your friend's ball and base your decisions off his PAP. Actually, trying to copy the layouts of other bowlers is one of the biggest detriments to bowlers and their games. No matter how skilled a bowler is, every person's game is different and there's no one-size-fits-all solution for how to drill a bowling ball. That typed, what is a positive axis point?
Locate the Track
The track, on your bowling ball, is the part of the ball that actually contacts the lane. You can see it after it comes back on the ball return. Look for the rings of oil. That's your track. The positive axis point, or PAP, is the one point on the ball that is equidistant from every point of the ball's track. Put another way, look at the ring of oil around the ball. There's one spot on the entire ball that is exactly the same distance from every piece of that oil ring. That one spot is your positive axis point.
Why Does a Positive Axis Point Matter?
The relation of the pin on your ball and the PAP is different for everyone, and crucial to getting the maximum performance out of your ball. If you use a drilling layout that puts the pin in an undesirable location in relation to the PAP, you're not going to consistently get the ball reaction you want. That's why it's important to base everything off your game and your style rather than trying to copy someone else.
Your friend's PAP location in relation to the pin may be great for him, but likely won't work for you. And vice versa. There's not necessarily a right or wrong, but the main point is it's different for everyone.
The Importance of a Local Pro Shop
Knowing your PAP is important, but if you're unsure how to find it, someone in your local pro shop will be able to help you. He or she will also be able to suggest ideal layouts for your style and game that will get you the most out of any bowling ball.
