Title: Asymmetrical Torsion Core, RG-Asy
Post by: plhaw on April 30, 2009, 01:17:25 PM

For the Asymmetrical Torsion Core balls, what does RG-Asy mean?  

Is this similar to RG-diff?  Do you add the two together?

I'm confused

If there's a number with it, I would think it represents the MB differential.  The higher the rating, the stronger the MB.  I don't really know what's considered high and low though, I would guess .02+ is high.

That is indeed the case.  The RG diff is the difference between the high and low RG values.  Those values are measured on an axis through the pin (call that spot x) and another axis 90* from the pin (call that spot y).  The RG-Asy is the difference in RG values as measured between y and another spot that's 90* from both, call it z.

The higher that differential, the stronger the asymmetry and the more influence the placement of the MB has on ball reaction.  Below 0.01", it's barely worth mentioning.  Around 0.015 it starts to get interesting, and when you get up to the current strong asymmetric cores in the 0.025 and 0.03 range, you can really make the balls do almost anything.

Thanks!  That was an excellent explanation.
