Effect of 5 inch pin on desired layout for 3 inch
« on: June 28, 2009, 09:39:30 AM »
Got a good chance to pick up a ball that I've been wanting to try at a great price. My favorite layout is (left hand) pin just above RF with slight cg swing.
I had a ball with a 5 inch pin a long time ago that I could never make a good reaction from, but perhaps it was my driller...
In theory, could I use a ball with a 5 inch pin to get a similar effect to the layout described above without screwing up top weight or anything else in general? What differences should I expect to see if any?
Thanks!

Lefty,

  A lot of information would be needed to make an educated guess. Much would rest on the existing topweight of the ball, or whether the ball is a symmetric or asymmetric ball.

 Also, the desired drill pattern would be greatly helpful.

A 5" pin will give you more drilling options than say a 2-3 inch pin. Remember static weights don't really mean anything anymore in ball reactions.

Rick,

While the static weights may not mean much, you still have to make the ball legal.  To do that, the OP may need a weight hole that gives him an undesired reaction.

I agree that the effect will depend strongly on the actual top weight and whether the core is asymmetric or not.  2oz of top weight, probably no big deal.  3oz or more and it could restrict what can be done with the ball and his favorite layout.  It wouldn't be undrillable by any stretch, but it may rule out the layout he wants.

I understand what your saying. But I would rather have a longer pin ball with heavy top weight than a short pin ball with heavy top weight. With longer pin balls you have more layout, drilling, and balance hole location options than you do with a shorter pin ball.

With shorter pin ball your options could be limited to pin down below the fingers which lefty50 wants above the fingers. With the statement of above the fingers I am guessing he/she is looking for the ball to respond to friction more quickly or a more angular breakpoint shape. a pin down ball will be more archly and respond to friction slower. With a pin up ball you have a lot more options for fine tuning reaction shape with balance hole locations and size. Also with the USBC rule change you can now use a 1 1/4" balance hole pitched and be legal.

Then you can use surface adjustments to manage reaction times from the first and second transition on the lane.

I do agree with Juggernaut that we need more info from Lefty50.
