For whatever reason (boredom possibly) I'm gonna mane a couple of more comments on this...
If anyone TRULY understand how a pin out or top weight is created, they would TRULY understand how trivially irrelevant statics are...1/32" shift from TRUE center of the mass creates (4.25" away) a 1" pin out or 1oz top weight. So if I cut the ball in half one side has 1/64" more mass. Static weights are just that, a weight gauged in a static sense not in a dynamic sense.
And anyone that has been performed TRUE tests and evaluations understands that one instance does not prove legitimate stats or proof just merely a limited instance nothing more nothing less.

Also in reference to the ebay ball being a 2nd why don't you call or email Brunswick to ask them why said ball would be a 2nd and give us your results?

My preception started changing when videoing my self showed me what I couldn't see or feel on the lanes.
Where and what I thought I was doing was not reality. It's not always easy to accept if you never allow yourself the chance to really see it.

Im an extremely stubborn person, but I know when to open up to new possibilities. Try going to bowling chat and ask other industry professionals your same questions so we can see what there thoughts are LL. Maybe you will find contradiction to better support your experiences.
