Unless I am mistaken, the max. leverage is the Pin 3 3/8" from the PAP and an earlier hook?

1. If the Pin is 4" from the PAP and under RF, this is supposed to give a bit more length....is that right???

2. If the Pin is 4" from the PAP and beside and above RF, that is supposed to give more length also, right???

Now, what is the difference between 1-2? What does each do?

Now, one more question on Pin placement:

3. Placing the Pin 5" from PAP and under bridge or MF

4. Placing the Pin 5" from PAP and beside and above RF

5. Placing the Pin 5" from PAP and directly over RF

Now, what is the difference between 3-4-5? What does each do?

Here are some general answers:

Yes 3-3/8ths is the strongest position you can place the core.

By placing a pin further away from your axis point what you are doing is decreasing the flare of the ball and allowing it to store more energy. So a ball with a 5" pin placement will flare less and store more energy than a 4" pin would.

When a pin is placed below your fingers you are drilling into the top of the core and lowering its RG value. So this will make the ball hook earlier than a ball with the pin placed about the fingers. In that case you are drilling into the bottom of the core and increasing the RG value...so more length. Pin next to fingers is basically splitting the difference. Typically people with a high track (horizontal PAP distance of 5-1/2"+) can have "thumping" issues when a pin is placed below their fingers...but that partially depends on the ball, drilling and bowler.

There is more to each concept, but these are the basic ideas.

In general I agree with Goof's post. However, there is one aspect I think should be clarified. Bowling balls do not store energy. As soon as the ball leaves the bowlers hand it begins to lose energy and axis rotation. Maybe a better way to put it is managing the rate at which energy is lost.

Thanks guys. It is a bit more clear to me now and Goof, you did a good job of making a clear understandable explaination.
