layouts for pin-in
« on: December 21, 2007, 03:56:52 AM »
Just generally speaking, what are the best options for drilling a ball with a 1-2 pin?  I'm looking for a length with stronger backend, and I'm a med speed/med revs bowler.

I would say go with a pin under middle finger or even pin in one of the fingers. These layouts will give good length and some good backend reaction.

You've been with Track for too long, what with the whole "ignore his PAP" thing.  Pin under middle might be 6", might be 4".  He didn't mention that he was drilling a Rising, so there's no telling what his PAP is.

What's the top weight of the ball?  Normally balls with a 1-2" pin get drilled with the pin below the finger line but depending on top weight that may not make a difference.  2-2.5oz of top weight and you can put the pin just about anywhere you want and keep the ball legal.

Chad, you mentioned you're a medium speed, medium revs bowler but you didn't mention what ball it was or what your PAP is.  The length you get will depend greatly on the ball, and some you don't want to use typical "length" layouts because they'll go too long.

Generally speaking, pin-to-PAP in the 5" range, even with or above the finger line, with the CG a comparable distance (for a symmetric ball) will give length and backend.  For an asymmetric ball, a similar pin placement but with the MB around 4" from PAP.  

If the top weight is higher, 3oz or more, then you'll be much more limited in what kinds of "length" layouts you can use.  A short pin buffer (put the pin around 5" from axis but close to the VAL) might work if you use a weight hole to get out the extra side and top weight.  Really, though, 3oz+ of top weight with a 1-2" pin is not the first choice for length.

He said generally speaking. So generally with a shorter pin, you would try to keep the CG stable so a weight hole wouldnt be needed. So to get this you would keep the pin under the fingers. So generally speaking I gave him a layout that could give good length for a short pin.

Yet things would change depending on the ball and his PAP.
