There is a lot of information about ball layouts. From books to articles in the bowling magazines to the internet. All those systems are doing is attempting to help ball drillers drill bowling balls correctly Most of the popular one are the duel angle, degree system, Storms Vector layout system, (X byY with buffers) plus the layout examples you sometimes get when you one buys a bowling ball.
Attempt at Drilling the Ball Right
All of these systems are attempting to one thing: Help a ball driller not to screw up a drill. After all, if a bowler pays $250.00 + for a ball, the ball driller AND the manufacturer want that ball to knock down a lot of pins. Do you think that a customer will buy a ball from that pro shop OR that brand of bowling ball if they are disappointed with the results? Players Pro Shop & Training Center uses theMo Rich DUAL ANGLE LAYOUT System to design precise ball reactions. The Dual Angle Layout Technique is based on the physics of the ball and the bowler's style and insures the bowler gets the reaction that matches their style.
All Systems Will Work - Providing:
All systems will work AS LONG AS THE BALL DRILLER KNOWS THE BOWLERS PAP, AXIS SHIFT, BALL SPED, AND BALL TRACK Why is that important? All bowlers do not have same release, ball speed or revs. Therefore their ball track, pap and axis of rotation will be different.
Average Pap vs Your PAP
Most drill sheets and layout systems assume a persons pap is 5 inches out and 1 inch up with a 45 degree axis shift. That is considered the norm. If your pap or axis is not those specs, then the targeted ball reaction will not be as promised. Hence, the more a bowlers pap and roll differs from the normal, the less accurate these systems are.
Another factor that drill sheets and drill systems cannot really account for is pin placements, especially in the case of asymmetrical bowling balls. Asymmetrical balls can have mass bias placements in really awkward positions, rendering a ball that can only be drill for a left-hander or visa versa.
Heavy Weight Block
Before Hammer introduced the hand grenade type weight block weighing several pounds, bowling balls had a weight block that weighed between 2-4 oz. This weight was designed only to replace the weight taken out of a bowing ball when it was drilled. Putting 4 to 6 pound weight blocks in a bowling balls made it mandatory that the layout of a bowling ball MATCHED a bowlers pap and axis shift.
Why Game Analysis Is Important
The above gives a person a general idea of why it is mandatory to analyze a persons games BEFORE they get a balled drilled. To do it any other way means the ball driller is either guessing or just doesn't care enough about the customer to get it right.
