Wax changes how the balls interact with the bed cloth and the rails. It has a great effect on draw and bank angles. Wax wears off in the course of the match.I just read this. Why not use wax? I'm having a feeling mine was also a bad reply. LOL
If you are the weaker player, it is a good way to screw up your stronger opponent since just as he gets used to the slip-and-slide, it goes away. Of course to actually do that in a match would be unethical. :groucho:
