Ball reaction
« on: June 17, 2010, 01:46:18 AM »
I was wondering what type of ball reaction would occur with a stacked leverage layout? Also is this type of layout better for symmetric or asymmetric balls?

Wrong question... Stacked leverage is one of the strongest setups you can chose for a ball - but pls read this correctly: it is about layout, not preformance. With this setup, you put the core in the most unstable position upon release, and the CG/MB marker promotes a strong hook due to lots of flare. Such a ball tends to hook early and a LOT, so it is - if you have a devent release, suited for long and oily shots where you need some extra help to get the ball from skid to an end roll.

Speed-challenged players will IMHO also benefit from such a layout, but the ball should be chosen wisely - if you have a low RG/high diff. piece, chances are high that the ball rolls out because its core migrates so early and strong towards its PSA. It dioes not make a difference whether the core has a low or high mass bias - but high MB cores will tend to migrate towards the intended PSA more violently and even quicker than simple pieces.

Covers have become so strong that such a powerful layout is hardly ever needed, though?

Just make sure the stacked leverage is layed out based on your PAP

And, as a side note: leverage position is just at the border that the core falls into a 90° rotational axis, if your PAP shifts just a little higher. The result is a much rollier, arcing reaction with little back end and poor hitting power - I have seen this happen several times (you can see that the ball starts rolling on its pin axis in the back end), so I would rather recommend a 4" pin to PAP distance, just to make sure you have some room for "changes"!

I would suggest finding a good ball driller that will actually get your specific information. PAP, Axis Tilt, Axis Rotation, Ball Speed, Rev Rate.

Then layout and drill a ball based on those spec's.
