Since the breakthrough of fine tuning reaction characteristics by use of the mass bias (MB) placements in the 1990's, large pin out balls have been a staple for many Pro Staffers on the professional tours. Big pin outs occur when the weight block tips to one side of the ball. The further the weight block is tipped, the more the mass is biased to that side of the ball pulling the Center of Gravity (CG) away from the pin. Advantages of these balls are:
With this layout we place the pin 4-¼" from the PAP. This position will produce medium to high flare, great for players trying to "open up" on a medium to heavy oil lane condition.
For bowlers with medium to high rev rate, this pin position will often produce the most overall hook throughout the entire lane!
Now select a MB position:
Be sure to check for excess side weight and finger/thumb weight, as a balance hole may be necessary for any of these layouts. If one is required, draw a line from the Center of Grip through the CG ad extend the PAL. This will be the location of the balance hole.
