Revs with a symmetric versus a asymmetric ball.........

[Hammer]

If I set up and throw a symmetric ball and then set up and throw a asymmetric ball throwing both the exact same way will the asymmetric ball have more revs because of the center heavy weight block versus the surface heavy symmetric ball? The different weight blocks compare to an ice skater with arms extended versus arms brought in close to the body. The latter will spin faster. Does this work this way with the two bowling balls with larger and smaller weight blocks?

I think you’re confusing symmetry with RG. A low RG ball will rev up faster than a high RG ball. Whether it is symmetric or asymmetric has nothing to do with it.

Exactly right. Revs are purely a result of the release of the bowler. The core will determine when the ball revs, not how much.

The low RG should rev up faster, but lose energy faster also. Rotational inertia in action. If you can get a higher RG ball to rev it should hold energy longer down the lane.

Just a guess from a physics teacher... coverstock will have a lot to do with the energy storage as well.
