The Rule seems to have fallen off the radar quickly. This is unfortunate, because it is a great ball. I love mine. I get a smooth consistent reaction. It is very easy to adjust the surface, and you can get many different reactions from doing so. I've had mine anywhere from 600 grit to highl;y polished. I like it at 600, but it does need a little oil to perform. When there isn't enough oil for my Animal or GP2 and too much oil for the 5.0's pearl cover, this ball is golden. Still one of my favorite balls. Thanks to Rick for punching this one up for me.
