We re often told two main things about how pin to pap distance affects ball motion.
Bowling ball pin layouts.
Typically a bowling ball layout favors the end over end path and it rolls around it s positive axis point psa or sometimes called the mass bias mb point.
The layout of course defines how the core is oriented inside the ball relative to the bowler s pap and relative to the gripping holes.
It is used on most house shots.
The ball s preferred roll is over the position pin and around an axis referred to as it s positive spin axis psa sometimes referred to as the mass bias point mb.
The arcing layout this is what i call the 90 degree layout or ebonite s 90 degree layout.
The bottom line is that it can matter.
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.
It is also used if the bowler wants to play the bowling lane at the track area or between the 13 and 8 board at the arrows.
The second image shows the path of the same ball drilled pin up.
This section details the different types of layouts that exist and the methods.
Given an infinite length and time a ball will eventually rotate around the pin either with the pin down on the lane or on top of the ball.
It is also the point around which the ball wants to rotate.
Methods used to lay out a ball.
Big pin outs occur when the weight block tips to one side of the ball.
The changes in bowling ball technology over the years have significantly altered how drilling the bowling ball will influence ball reaction.
Pick your favorite layout.
X place pin 4 from pap use 2 pin buffer locate key 4 from pap 7 layout 3 for maximum control with a flat shape and very little taper the sport shot is very challenging.
The pin marks the top of the core inside the bowling ball.
Pin down layouts give you a slower more controllable overall ball reaction.
Also t he layouts are for right handed players.
What is a pro pin bowling ball.
Pin to pap distance is one element of a bowling ball s layout.
On these demanding.
Pin down drilling layouts allow you to stay in the same area because the ball reaction is not as aggressive.
The days of a pin up ball going farther down the lane and a pin down ball starting sooner are gone if we hold the other variables constant.
Positive axis points pap your layouts may not have the same appearance as the illustrations.
However if you average less than 180 don t be so concerned about having a pin up and a pin down ball.
One consideration if you don t have a high rev rate or high ball speed is that you normally want to change to a similar bowling ball with a pin down layout.
