Please Note: Because all
bowlers have different positive axis points (PAP) your layouts may not
have the same appearance as the illustrations. Also the layouts are for
right-handed players. Remember to flip or rotate to produce
"mirror-image" for left-handed players.
Pro Drilling Instructions
Note: For reaction
adjustments, consult the Ball Surface Reaction Guide.
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 the grip through the CG and
extend to the PAL. This will be the location of the balance hole.
Layout 1
With this layout we place the pin 5-¾" from the PAP, above the
finger holes, to produce length on drier conditions.
Next we select a RAD position suitable for our breakpoint shape.
(A) Rad in the Ball Track designed to produce a late
and smooth breakpoint.
(B) RAD in the Strong Position This will produce an
earlier and shaper breakpoint than Position A.
- Good for extreme entry angle!
(C) RAD on the PAL produces the earliest breakpoint of
three positions while providing a controllable and "readable" backend.
- Works great on heavy oil patterns!
Layout 2
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 rates, this position will often
produce the most overall hook throughout the entire lane.
Now select a RAD position.
(A) locate the RAD halfway between the ball track and
PAL to produce a sharp breakpoint
(B) Place the Rad at the PAL for an earlier, smoother
breakpoint.
(C) Place the Rad 2" past the PAL for a very heavy
midlane roll on long oil patterns.
Layout 3
Place pin and CG 4-½" from PAP.
Use scale to determine static balance.
Produces length and an arcing backend.
A layout every player should have in their bag.
Layout 4
Note: To remove excess finger weight, drill finger
holes 2.5" deep.
Place pin and CG 3-3/8" from PAP.
Use scale to determine both side and finger weight.
Locate balance hole on PAP and remove excess side weight to ¾ oz
positive.
Produces maximum flare and hook
Works especially well for Tweeners and Strokers!
Layout 5
Place pin CG 5-½ from PAP.
Locate RAD in between ball track and strong position.
Use scale to determine static balance.
To locate a balance hole if necessary, draw a line from grip center
through CG and extend to axis midplane.
High track players will benefit from this layout.
Layout 6
Place pin and CG 4-½" from PAP.
Place Rad on the axis midplane.
to locate the balance hole if necessary, draw a line from grip
center through CG and extend through axis midplane.
This drilling will help generate more midlane roll.
