Ah, my question was a result of "logic by way of extension" -- you used this deduction:
"If it's a mudball, then it was designed to be used on a coin-operated pool table...so that means it'll follow a magnet...meaning it has metal in it in one form or another....so, see if a magnet pull the ball along a flat surface....if not, then it's not a mudball"
...which, if we read it the way it was written, you imply that "any" ball that follows a magnet, "is" a mudball. If it doesn't follow a magnet, it's not a mudball.
So we know the Aramith green "S"-logo'ed ball will follow a magnet, but most on these boards will tell you that it's not a mudball.
Excellent piece of information -- thanks for sharing! Although methinks you might've let the secret out.
I do have one of these green "S"-logo'ed balls, I've obviously not cut one in half, because it's the only one I own, and I need it. If, like Craig, I had several of these laying around, being the science-minded person I am, I most definitely would've taken a band-saw to one.
I can tell you, though, in comparison to the traditional mudball or even the traditional "plug" ball, this green "S"-logo'ed ball reacts differently. I've had people swap the ball out in the middle of the game (without the shooter knowing), and the shooter slammed the p!ss out of it with draw (expecting the lackluster draw response from the mudball, and obviously compensating for it), and the Aramith ball slammed in reverse and went zinging around the table. The shocked look was priceless.

That's because Aramith did a better job on the finish of the "New" magnetic cue ball to hide the pluged look, and to keep the finish lasting a little longer than the "mudball" so the new finish cuts down on the friction drag when trying to back spin the cue ball therefore making it easier to "draw" the cue ball back-wards:grin: but still most of them "S" magnetic cue balls still don't roll straight!
