I decided to bring my Grand Illusion surface back up I had 45 games on it and was noticing the reaction tapering off.  Following Roto Grips instruction I took sanded first with 1000 followed by 2000 on the spinner and topped it off with a coat Snake Oil instead of the Storm Polish.  After working my way through two splits and a blowout I managed to finish with a 222 my first game and a 245 the second game in league.  The Snake oil gives me the length, but does not cause the ball to over react on the back end.  Thumbs up on this product.
