nice job nick. it's interesting to note that like nick said there are still some people who don't realize that the surface of the ball plays the biggest role in the balls reaction. and the next biggest influence is the position of the pin.

position of the pin in relation to core dynamics has a bigger influence, like everything if you take a pancake block and move the pin around it is minimal where as a ball with a dynamic core will see a bigger influence with pin placement. Meaning in my book, core shape/dynamics is what has that influance on the pin placement. Just my 2 cents as i feel core shape plays a more vital roll then some give it credit for

Nice read.
Good job Nick

Trigg, what if you compared a XXXL to a pancake core resin ball? (i.e. Scout, Tornado Warning)

Sure, you'd be able to alter flare and ball roll, but without the surface causing more friction, the results are null. The resin pancake ball will outperform the plastic based on surface and surface alone.

i was lucky enough to meet marshall holman several years ago and he told me that he couldn't believe the difference the outside of the ball made when comparing his plastic yellow dot to the new urethane u-dot----both of these balls used three-piece construction.

I agree with that somewhat Nick, but, I had a reactive hammer claw, weak reactive, pancake block, my xxxl did indeed move more on the back part of the lane, the pancake block was rollier. I dont argrue that surface is the determining factor as I know it has the most influenence, my contention is that core shape and dynamics is what lets the pin position do its job, pin placement is puting the core in anywhere from a stable position to a very strong jerky position

two balls same cover, one pancake block one dynamic block, pins in same position, the cored ball will react differently

surface 60-65%
core dynamics, 20-25% (this includes pin positioning since you have to put the core in an angle to acheive those motions)
x hole 5-8%
statics 3-5%

all I am saying is to say that pin position is the second biggest factor is not entirely true, it is core dynamics and the way you place that core vs a bowlers sytle/rev rate/axis tilt that defines it, with surface being a friction device, as it slows it is then up to the core dynamics to "finsih" off the movement, back to your plastic discussion, not enough surface will not allow the motor to work. surface alone will not get the ball to roll over and get into a stable roll which leads to those bone crushing strikes everyone likes to see

I see what you are saying now and I agree to an extent.

I still think a high rg, low diff core ball with a particle cover like the Mammoth (or even a Wizard) will outhook a low rg, high diff core ball with a mild pearl resin cover like the Groove.

It all comes down to what you think hook actually is. Sure a ball that retains energy for the backend, and creates a "jerk" will appear to hook more than a ball that gradually makes a strong break. This could be a topic for an entirely different article. "What is Hook?"

Nice article!

T-GOD · « **Reply #13 on:** August 17, 2007, 02:44:57 PM »

Nick, you talk about mass, mass bias and moving mass. Depending on where the "mass" is, and how it's situated in the ball, the mass will determine ball motion. Correct..? =:^D

Can you be a little more general?
