Long pin Vs. short pin
« on: February 23, 2010, 10:45:54 AM »
"Generally speaking", what's the difference if 2 of the same balls( 1 with long pin and 1 with short) were drilled the same way( say pin below ring finger). Would one hook more or have better control over the other?  Thanks!

If you're talking about pin-CG distances (vs pin-PAP distances):
Longer pins take longer to go through the skid/hook/roll cycle.
Shorter pins go thru the cycle quicker.
Longer pins usually make for more versatile drilling options.
Shorter pins make for less versatile drilling options.

Middling pins, 2-3" and 3-4", you can do a lot with.

Jeff, thanks again but sorry still not 100% clear

Say my favorite drilling: pin below ring finger.... but all my balls have a 1-1/2 to 2 in. pin. I just got a new ball with a 4 in. pin. So where should I put the pin to get a similar reaction?

This is all about static weight. CG is just the heavy spot on the ball. If you have a long pin it will roll like a ball with thumb weight and a short pin will be closer to neutral. It really doesn't matter that much.

The pin location has the biggest effect on the balls reaction and core location. So if you had two identical bowling balls one with a 2" pin and one with a 4" pin and you put both pins in the same location then the only thing you have to worry about is the final destination of the cg and how much weight it carries.

If it has light top weight you can easily manipulate the depth of your fingers and thumb as to not require a weight hole on a long pin ball. If it has heavier top weight you may then need to add a weight hole or drill the fingers shallow and the thumb deeper to help keep the ball in legal weight.

You can also kick the cg out on either and add a weight hole that can increase or decrease the balls reaction. See link below from brunsnick.com

AS far a I have learned -
A lot depends on your ball speed. The higher your ball speed the less difference you will see. The slower the ball speed, the bigger the difference.

If you went from a 1.5-2" pin-CG to a 4", I'm not sure you can drill them to see the exact same ball reaction, again depending on your ball speed. The pin position will change the flare and can change the breakpoint shape (disyance from VAL). With the same pin position, the longer pin will seem to go longer with slightly more backend.

Thank you guys! I'll just make sure if a weight hole is needed in case I have the CG kicked out.
