Hey Moon,
You must have received one of the original flyers instead of the corrected one for some reason. The 1/2" pin on the AMB Particle is white, and the locator pin is actually clear, but looks black inside the ball cause light doesn't penetrate it. The VMB is directly opposite the locator pin, or 13.5" from the locator pin through the white flip pin.
As far as the CG goes, they are correct. The CG is always marked with a small circle above the serial number. We haven't changed that.
Another way of looking at the drilling, is simply to mark a spot 6 3/4" from the white pin through the cg. This should be nearly identical to the 13 1/2" method, however it is not quite as accurate because the CG could be slightly off centerline. HOWEVER, all of our balls are checked to make sure that the CG is very close to being in center, so it wouldn't be off by much.
