CG PLACEMENT QUESTION

[Linknblue]

I want to layout a ball that has the pin 1 to 1-1/4" from PAP. It's a symmetrical ball with a pin to cg of about 2 1/2". RG of 2.54 with .032 diff. Simply light bulb core. Where should the CG be placed now that you can't drill weight holes anymore? I had one a few years back and I remember the CG kinda stacked with a weight hole down by thumb hole.

As long as the top weight is less than 3oz, anywhere on the gripping hemisphere of the ball.

CG on a symmetrical does not matter at all. When you were allowed weight holes you would leave some side weight so you could add a balance hole but with the new change you can place it pretty much anywhere and still be legal with side weight. Placement will have zero effect on the drilled balls performance.

^^^ This. It's really only surface and pin-to-pap distance in terms of tweaking the reaction of symmetric balls under today's rules.

So if I opt for a symmetrical ball, lay-outs are like 20 years ago. Pin distance from PAP is really the controlling factor (and surface)? Does pin up still mean "goes longer-hooks sharper" and pin down mean "rolls earlier and milder reaction"? CG location doesn't matter? Used to be CG toward center, CG stacked and CG swung out. Forget that cuz surface will fix whatever you want it to do (hook early or go longer)?

Pin Up: Faster Response to friction (taller core, higher diff)
Pin Down: Slower Response to friction (fatter core, lower diff)

Coverstock is the dominant factor in length, not core dynamics.
