Pearl comes from mica, which increases surface roughness. In my experience, pearl covers read friction harder, not increasing skid.

Larger cored symmetrical, and also asymmetrical balls, allow strong drilling techniques to enhance the ball motion more than smaller cored balls. This makes them more versatile by changing the drilling technique. Enhanced diffs. and diff. ratios result in sharper break points and faster transitions which most times increase carry especially for weaker handed and higher ball speed players.

Changing the flare will affect both transitions, but affect the first transition the most.

Lower the drilling angle and cut the VAL angle half the amount by which you lower the drilling angle. Consider a more flaring pin to PAP distance.


Question:
As a rule, if I wanted more midlane would I:
A. Adjust the Drilling angle down?
B. Adjust the angle to the VAL up?
C. Adjust the surface up or down?
D. Abandon all hope ye who enter here?

From: "? on control layouts and more midlane"

"Flare management is mainly used to help determine the length on the lane of the first transition when it is used properly. That's about the jist of it."

Some bowlers were saying that as long as flare rings were hitting a fresh surface, anything else was overkill. see viewtopic.php?f=13&t=6086" onclick="window.open(this.href);return false;

Mo's correction:
"Stop using the distance between flare rings to measure flare! Try using the total distance that the precessing PAP moves in relation to the major and minor axis of the RG contour to accurately evaluate the amount of flare necessary for good ball motion. Now we're discussing reality, instead of just looking for things to talk about."

How many degrees do you add to sums for low tilt & low rotation? Found in discussion:
viewtopic.php?f=15&t=6158&view=unread#unread" onclick="window.open(this.href);return false;

10* for tilt and 5* for rotation are the approximate guidelines that I personally use.

Taken from pap location measurement options discussion:
viewtopic.php?f=13&t=6301" onclick="window.open(this.href);return false; (#6)

"Please bear in mind that the PAP at the point the fingers exit the ball is very consistent. That's probably why blueprint uses that point. But, even though balls don't hook in the air, they still begin precessing the instant the fingers exit the ball. That alone will cause some variations in PAP for different balls. This shows up when measuring the difference the PAP of flaring balls vs. non-flaring balls, which usually approximates 3/8". And, also, bowlers are humans, even though they don't always act like it!"

Same discussion:
"In the real world, the PAP that is used is determined by the first oil ring. So that's the PAP of the first revolution of the ball that's in contact with the lane. The axis migration that takes place before the ball hits the lane can't be measured in the real world."

The quote here is by Mathistruth. See the thread for discussion and explanation by Mo and others.

There are 3 phases of ball motion, the skid phase, then the hook phase and finally the roll phase. The first and second transitions is what we call the points which seperates these phases. The skid and roll phases are linear in nature which means linear equations can be used to model the ball motion. The hook phase is modeled by a quadratic equation. The vertex of that parabolic curve coincides with the breakpoint. It occurs somewhere between the first and second transition.

Here's the real answer about reverse oil. Reverse oil controls the amount of oil in the front part of the lane. Forward oil controls the shape of the pattern at the end of the pattern. The more reverse oil in relation to the forward oil, the longer the pattern last and the smaller the transitions. Read the pdf and find the corner of the red bar. Subtract 3 and that's where your breakpoint should be to start. Take the length of the pattern minus 31 rule and shove it. Not accurate. Do your homework!

Here's the English lesson. Continuous means a longer, more gradual hook. Sharper means a shorter, more violent hook. The total amount of the change of direction is not related to that. A shorter, sharper hook could result in more entry angle than the longer, more continuous hook. Everything discussed in the podcast is in the Wiki. Please do research in the Wiki.

from discussion of a Double Thumb layout for low tilt/high rotation bowler:
viewtopic.php?t=354" onclick="window.open(this.href);return false; (see #6)

The P3 hole will make the difference as opposed to the "Double Thumb" balance hole location.

The key factor is your 70* of axis rotation in conjunction with 7* of tilt. We're getting into PDW territory. The P3 hole will help control possible overreaction and make the ball more controllable, but still very strong.

"I use 4 1/4" as the maximum depth for drilling holes. The Jayhawk chart is for mass removal, not change is static weights. Think spherical geometry!"

On balance holes. Deeper and smaller diameter v.s. shallow and larger.

"Let me clarify what you're saying. Those holes will remove the same volume of material. Whether, or not, they remove the same mass depends on the densities inside the ball. The deepest hole has the best chance of removing the most mass because the densest part of the ball is the inner core, which is in the center of the ball."

"On asymmetricals, reducing pin to PAP distances from 3" reduces flare, thereby getting the ball down the lane further.

On symmetricals, increasing pin to PAP distances from 3 1/2" reduces flare, thereby getting the ball down the lane further."

Mo is actually the author of this Thread:
viewtopic.php?f=13&t=6710&view=unread#unread" onclick="window.open(this.href);return false;

"Timing is NOT related to when the bowler pushes the ball out. The bowler will push the ball out in competition when they are ready. Timing is related to:

1) Grip pressure
2) The length of the hinge
3) The half period of the pendulum

This should stir the pot a little.

Increase the timing window by increasing the flat spot to improve timing.

OH BOY!"

Mo's answer to a request for a definition of a performance fit.

A performance fit is a fit adjusted off a good basic grip that changes the natural effect of each of the fingers and the thumb on the ball motion that results from the bowler's basic (Wiki) grip. The purpose of the performance fit is to adjust the axis tilt, axis rotation, and speed, or rev, dominance of the bowler's natural delivery in order to improve the effectiveness of the ball motion. Basically "training wheels".
