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. .

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.
