Anything that I've heard about the Rule is not good. When it came out is was not good, which is not characteristic of Track balls. Therefore they came out with the Xception which is very skid-flip and performs very well.

"It all comes down to this roll. Roy Munson, a man-child, with a dream to topple bowling giant Ernie McCracken. If he strikes, he's the 1979 Odor-Eaters Champion. He's got one foot in the frying pan and one in the pressure cooker. Believe me, as a bowler, I know that right about now, your bladder feels like an overstuffed vacuum cleaner bag and your butt is kinda like an about-to-explode bratwurst." Bill Murray--"Kingpin"
