On higher track (lower tilt) players, I try not to use pin to PAP distances in excess of 4 3/4" because it can pull the track up on the holes. It doesn't happen all the time, but it happens often enough for me to avoid it.

Note - in a subsequent post Mo says that applies to both symmetric and asymmetric balls. -- JohnP

Personally, I use that 275 rpms is matched to 17.5 mph.

If you describe it accurately, the transition is too short. That is altered by changing the mass properties of the drilled ball, thus, the balance hole is the answer. Surface changes the first transition.

I try the balance hole first, then, the surface. Just my habit.

Those balls have generic symmetrical cores under 14#. The only thing similar to a real Fear Factor is the coverstock and the logo.

Without a DeTerminator, you're screwed, and not in the right way.

"The P3 gradient line hole will make the ball reaction stronger because it will increase both diffs. The VAL balance hole will only affect the first transition by making it start up sooner as you make the hole bigger. This is because that hole will move the PSA closer to the VAL as you make it bigger."

That quote is specifically about symmetrical balls!

I'm not versed enough on that math to comment, but have experience with abrasives and smoothing of surfaces. Regular surface scratches can create harmonics and tend to promote smooth, continuous motion. Irregular scratches tend to interrupt motion and can be used to increase the rate that balls transition. This is the basis for my "skip a grit" finishing technique used to promote earlier transitions and, therefore, help the ball read friction by helping to interrupt the skid phase. I keep recommending "true" grit sequences to promote smooth, continuous motion and "skip a grit" grit sequences to encourage the ball to transition faster.

Q. What layout does everyone use for the THS when they get real wet/dry ?

A. Use a larger VAL angle than normal and a longer pin to PAP distance than your benchmark layout.

Speed, or rev dominance, affects the sum of the angles and the pin to PAP distance. Tilt and rotation affect the ratios.

By Kelly Tehuna, confirmed by Mo.

From: viewtopic.php?f=15&t=5447

This bowler has high axis rotation, which means we need to get the ball to roll forward as soon as we can. In asyms, longer pins promote more forward roll, while the opposite is true of syms. So, if we need the ball to roll forward off the end of the pattern, long pins will be the order of the day for asyms, and short pins for syms.

Balance holes affect reaction more than the layout. 60% effect from balance holes and a 40% effect from the layout. I'd love to answer you, so can you reword your questions in this case.

Here's how it works. When the lane transitions and you lose your reaction, make small physical adjustments (hand positions, ball height, eye distance) to regain the reaction. If that takes you out of your game, switch to the ball in your arsenal that gives you that good reaction with your "A" game. Not too bad! That just requires you to have a well developed, versatile physical game, an eye for ball reaction, and a well thought out, effective arsenal. Simple, heh?

"Again, we're dealing with labels and semantics. Understand the three phases of ball motion thoroughly. A bowling ball hits best when it has reached the third phase of ball motion, the roll phase. In the roll phase, the ball has lost all of it's skid factor and, therefore, is at it's highest rev rate and has 100% traction. That is the real answer. No matter how much ball speed, rev rate , axis tilt, and axis rotation the ball is delivered with, the ball must reach it's roll phase before it hits the pins in order to maximize its' hitting power. End of statement. No semantics!"

The DT layout will maximize the diffs. of the drilled balls, therefore, making those layouts the most responsive to friction for those balls. With some players and balls, that means soonest, and, with others, it means hardest. It depends on the player, the ball, and the lane condition.

Q. I have a question regarding Gradient line balance holes on balls on which PSA ends 1/8" - 1/2" past VAL line (I drilled few balls with larger VAL angles and smaller horizontal pap coordinates where this happened). I wanted to know does everything stay the same in those situations (6-3/4" up the VAL from PSA-to-PAP and PAP-to-PSA line divided in 4 points)? Will this cause any issues with flaring over balance hole if I drill P4 holes?


In this situation, P1 remains the same. You are right about the guidelines for positioning the P4 hole. Balance holes should not be placed below the thumb or past the VAL to prevent the ball from possibly flaring over the balance hole. We use the "Double Thumb" position when the P4 hole position is below the thumb hole. In the case where the PSA is past the VAL, use the intersection of the pin to PSA line and the VAL as the P4 position to keep the balance hole flare safe.

" The diff. ratio is the intermediate diff. divided by the total diff. Using that info, undrilled symmetrical balls have a diff. ratio of 0 because they have no int. diff. Undrilled asymmetrical balls have the diff. ratio calculted by the int. diff./total diff. Layouts change those numbers. Drilled symmetrical balls have int. diffs. created by the layout. Driilled symmetrical balls almost always have lower diff. ratios than drilled asymmetrical balls, unless the asymmetrical balls are drilled for control."

With the much stronger covers that are available to use now, lesser intermediate diffs. are used to manage the ball motion better. Higher int. diffs. would produce to early a 1st transition too often.
