core shape.. mass on top vs mass on bottom
Trying to find some information about how a ball will roll and react differently if the mass of the core is closer to the pin vs on the opposite side. I had just run across something that talked about this, but I can not find the article. .
Right Handed, 16-17 mph off hand (14 -15 mph on Qubica reading) ,350 rpm,PAP 4 3/4 x 1/4 up, 17 deg axis tilt, varied rotational axis deg.. usually 45+

Re: core shape.. mass on top vs mass on bottom
I had not seen this before, but this does have the information I was looking for. What I saw before was just a couple of lines, I think from Mo, in one of the Wiki docs.
This was pretty good though. Thank you.
