There's also some mis-information and generalisations in that video. They are not being made by a bowling coach.

Right, sorry about that:

Speed: 14 off her hand
Rev Rate: 380-400
Initial Axis Rotation: 65
Initial Axis Tilt: 8.3 (12.25 inches)

I'm looking for a very arcy motion. Not snappy at all.

Hi, have you got any video of her bowling? I'm curious as to how she gets 400rpm at 14mph off her hand.

With the allowances of 3oz side weight, you should be ok to use smaller drill angles on an asymm ball.

Bad luck? Good shots that don't get rewarded via pins getting knocked over then standing up or sliding across and not falling.

Good luck? Throwing a terrible shot and still getting a strike.

Both happen.

Well, sure. In basketball, a 3 pointer counts as 3 whether it’s a swish, off the backboard, or takes 8 bounces off the rim. In hockey, goals can be scored by bouncing off a guy who was lucky (or unlucky) enough to be standing at the right place at the right time. There’s the racket sports, like ten...

It still disturbs me that activities like women's softball and snow boarding are Olympic sports, but bowling isn't? Really? I mean really? Snow boarding? Olympic Sport? You also left out BMX racing. First off, I love bowling, but can you name one Olympic sport or event where a mistake is rewarded w...

I can't find the thread as well but I knew I have it written in one of my notes and found it 70 x 3 x30 for Asymmetrics

Thanks for that, I've got an asymm ball to drill so will give it a go.

If you can find me a drill bit long enough, I'll do it!!

With the change in USBC rules, there goes my favourite layout and secret weapon, the Motion Hole!! I like to use it on medium to strong reactive solid symm core balls. With my PAP, I use a pin beside ring layout and motion hole, but with the hole plugged, the ball will go from a long and strong layo...

Bill Sempsrott wrote an article in BTM recently examining the proposed changes, and opening up the static imbalance limitations can allow for more performance than what weight holes can currently provide. He concluded that seems a step in the wrong direction if they want to limit ball performance.

This is something I've been thinking about a bit lately, and am curious if anyone knows the answer. If a ball is bowled with negative tilt, say -5 degrees, does it stay at -5 the whole way down the lane, does it get more negative, or does it want to get back to 0 degrees, like a ball that burns off ...

G'day Bahshay, attached is some info for you to consider, looking at what Jim mentioned and a few other factors.

Thinking about this more, another quirk in the numbers seems to arise when shortnening the span to allow for more fwd in the thumb. For e.g. If my Middle Finger span was 4 1/2" and I had a 90* thumb angle, I woud get 1/4 reverse in my thumb linear pitch. If I adjusted that to 1/4 forward, my span wo...

The original span-to-thumb pitch chart is in Bill Taylor's book on fitting. In it he states that the span to pitch relationship is used to maintain a 63* angle, which he says is the optimal release angle. For this reason I would think that you'd need to base it off the thumb pitch you actually use....

Hi all, I have just rechecked my grip as it had been nearly 3 years, and when going through the process a question arises that I don't recall seeing the answer to. Using the Morich fitting system, my recommended fit is: Thumb Pitch 7/16” Reverse (90 degree ave tight + 1/8" reverse for long thumb) 1/...

Here are some old examples from Mo I have on file of higher tilt suggestions: Axis Tilt: 20 degrees Rev Rate: 360-370 Speed: 16.76 (ave speed hand to pins) Axis Rotation: 55 PAP : 5 3/4" by 1/2" Mo: With 20* of tilt, I like pin to PAP distances of 4 ¼" to 5 ¾" on asymmetrical balls and 2" to 3 ¼" on...

So Dean, do you have any ideas just what they are doing to achieve this? What kind of equipment are they throwing in situations like this? They are using polished balls, slightly speed dominant with side roll and higher tilt, and incredible touch and speed control. They also have a bit of left to r...
