whats the difference between a ball with a long pin against a ball with a short pin? How long is long and how short is short? would there be any difference in reaction? thanks

The answer to your question is a generalization so my answer is too.
The difference between a pin in of 0" and Pin out of 6.75" which to me is the min and max for all intensive purposes is 10%.
Example (hypothetical):
Both balls drilled the same with same static weights, surface, and condition;
Pin to CG distance of 0" rolls at 40'
Pin to CG distance of 6.75" rolls at 44'.

I have no data to back this up, but it is my observation from experience of the same ball that was pin in & out (.5" vs 3.5" *5% roughly*).

The longer pin ball was more skid/flip and the shorter was smoother.

The difference comes into play mainly when you're dealing with a customer that prefers to not have a balance hole. With a longer pin (3 - 4"), you can use almost any layout and still keep the pin in the safe zone and far enough away from the finger holes to keep the warranty in effect while keeping the cg in the palm. With a shorter pin, it may be impossible to use the ball for a high track bowler without flaring over the finger holes (again, without drilling a balance hole). -- JohnP
