More than ever, we are seeing issues regarding breakage or the slug getting stuck in the ball. It doesn't seem to matter what brand either.

I would like to hear your experience regarding inter-changeable thumb slugs.

Through my many years and a handful of different bowling centers, creating a satisfying, high scoring, league (house shot) oil pattern has always been a challenge. There are too many variables that need to be considered, each and every center plays differently. My personal experience, without fail, ...

Great!

It would have been an extremely lucky guess to come up with that modification without seeing you in person.

People age differently and physical condition of the bowler could play an important role in your grip specifications. Is it possible to change pitches while leaving the span? That answer would be yes. But, usually, the span might be altered accordingly.

Rolling a bowling ball effectively takes good timing. Putting the ball into the swing motion a little too late or too early causes all kinds of release, speed, and accuracy issues. And...a thumb hole that is too large can make those issues even worse. ***Utilizing a four step delivery does not neces...

There are so many other factors to consider when analyzing a person's grip. Charts simply give the pro shop a reasonable starting point.

The person is a very good bowler too. He is a high torque, high rev player, his technique is solid. From every perspective, it looks like his delivery / release never changed. He had been scoring well, nothing warranted a closer look. Recently though, we drilled a low flare layout based on his old t...

Has anyone ever encountered a situation where a bowler's pap changed dramatically? The original stats were 5 3/4 x 1/4^. The new pap is 3 1/4 x 2 1/4^.
Personally, I have never seen a pap ever change to that degree.

There are two notable no-thumb layouts, one is the 2LS (Storm Layout), and the PAL (Mike Pinel).

Which do you use and why?

All bowling centers are different. If you find a combination that works at a certain center, it would be a good idea to make a note.

Nothing is simple in this game anymore. There are so many different types of lane surfaces it'll make a person's head spin. That does not include the overall condition of the surface either. You should stay with the shoe / heel combination that allows you to slide. Sure, it may feel like you can bar...

Pin pointing the exact feel you're looking for is probably going to be a trial and error process. If you use a rotary tool, you'll be changing the texture of the entire hole. You could etch the slug by hand. This would allow greater control over the process. I've seen people use a nail to scratch ho...

Falling on the approach is one of the more tramatic events that can happen in a bowling environment. It happens suddenly / unexpectedly. That sensation sends just about any person into a life preservation mode. Getting your confidence back will depend on you getting comfortable again. In today's bow...

after a ball is drilled and in use, can It be changed over to interchangeable thumb inserts without being plugged. Do they just drill out the thumb slug and install a changeable thumb insert? In most cases, interchangeables can be installed in the ball without having to plug the thumb hole. *There ...

I wonder, has “the weight of the ball” issue ever been established through the use of a robo bowler?

Agreed, when a bowling ball comes in contact with friction, that torque created by the core of a bowling ball is a factor. (We all know the coverstock has a lot of influence). In the video, given that the coverstocks are relatively the same, the difference between the lighter ball and the heavier ba...

One factor I have never heard anyone talk about is torque. Torque would be the amount of force that is applied to the bowling ball at the point of release. I guess, it is not measurable? The heavier the ball, the greater the resistance. But, it is not just a weight factor. Rolling a heavier ball req...

The foul line drill is very effective, used it extensively while coaching at the collegiate and high school levels. It was somewhat frustrating to see a few people not benefit from the exercise. This particular group of people would constantly accelerate the swing too early even while doing the foul...

Over the years, I've had several bowlers that were very good athletes. All had above average fast twitch muscles. They all had a couple things in common too, turning the ball early and turning it violently. Try as they might, they just could not stop releasing the ball so violently. In an effort to ...
