"Many of the tips on this web site describe the influences of the
bowler's style and the dynamics of the bowling ball's core, pin
positions, CG positions, and balance holes. Their order of
influence in the ball reaction equation, from most to least, is as
follows:
1. Bowler's style and lane condition
2. Ball Choice (RG, differential)
3. Pin Position
4. Mass Bias location (for asymmetric balls only)
5. Balance hole size, depth, and location
6. CG location
7. Ending static weights (side weight, finger/thumb weight,
top/bottom weight)
