Here's what I'm getting at:
Low Rg = core heavy, High rg = cover heavy
Taller core = Low Rg, Thicker cover = High Rg
In an asymmetrical ball the axis where the core is the tallest, the pin, is the low Rg of the ball. The axis where the core is the smallest, the PSA or mass bias, is the high Rg of the ball. The line between the two, the line of most resistance is where the Rg climbs the fastest from low to high. This is how an asymmetrical ball works. As your axis(PAP) migrates towards this line, Rg increases and the ball fights revving up. Once it crosses this line, Rg decreases and the ball revs up easily.
Now you say I'm getting off topic, but take a look at the Rocket core:
http://www.ballreviews.com/Reviews/Reviews.asp?ManufacterID=2&BallID=769The portions of the core with the "fins" are wider than the portions without. The Rg is higher in the portions between the fins. As your axis migrates towards one of these fins, is will rev easily. Once it passes one of these fins, it will resist revving until it hits the center of the non-fin area. If the fins are located at 0, 90, 180, and 270 degrees, then a 90 degrees shift of the core will give you almost the same orientation. A 45 degree shift, on the other hand, will maximize the change in orientation.
In his experiment, Nick used a ball with a diamond core and no I hope you can see the mistake in choosing that ball. He chose a ball that supports his main defense, spinning the ball around with the pin constant won't change orientation much. The problem is that not every symmetrical ball follows this rule.
