What is the difference between asymmetric and symmetric bowling balls?
It’s generally accepted that symmetrical drilled balls have a smooth, controllable motion. Asymmetrical balls have a defined, angular shape downlane that respond to friction quicker than symmetrical balls, given the same coverstock composition and preparation.
What is PSA on a bowling ball?
The preferred spin axis (PSA) on an asymmetrical ball is one of the most misunderstood topics surrounding bowling ball technology in today’s game. A majority of bowlers don’t realize how important it is and how much more the ball reaction can be fine-tuned when drilling an asymmetrical ball.
How tight should thumb hole be in bowling ball?
You want your thumbhole to feel loose, but it needs to be tight enough that you can release the ball without gripping it. You shouldn’t need more than a piece of tape to accomplish this.
How tight should your fingers be in a bowling ball?
When you place your fingers in the ball, they should slide comfortably to the first crease down from the fingertips for a standard “fingertip” grip. If you’re jamming the fingers in because they’re too tight, change the inserts or have the holes opened slightly.
How do you find the center of a bowling ball grip?
Start by finding a bowling ball with a track, or a fresh oil line on the ball. Trace the track closest to the holes, and follow that tracking line around the ball. First mark your grip line. Then find the center of your grip, and draw a line perpendicular to your grip line.
How should my ball be drilled?
For most performance core shapes, in order to change the ball motion measurably, you need at least a 1” drill bit going 2 ½ inches deep. Whether drilling pin up or pin down, most of the time drilling the finger holes will only have a slight impact on the ball motion.
When should you use an asymmetrical bowling ball?
Asymmetrical balls are great for heavy amounts of oil or longer patterns which don’t provide a lot of friction while symmetrical balls are typically smoother and yield a benchmark type of reaction that are more controllable.
Does pin to CG distance matter?
Re: Pin to CG distance It doesn’t really matter. I requested a 3-4″ pin from Motiv and for some reason the ball i got only had a 2 1/4 – 2 1/2″ pin. I still used the same layout i planned on using. Any knowledgeable pro shop will know how to get a ball legal.
What does RG in bowling mean?
radius of gyration
Measured in inches, radius of gyration is the distance from the axis of rotation at which the total mass of a body might be concentrated without changing its moment of inertia. Simply put, RG is when your ball begins to rev up. Low RG bowling balls rev up earlier on the lane than high RG bowling balls.
