This rubber is highly sensitive to relative humidity !!!
In dry weather it is an awesome rubber. Lots of spin, acceptable speed, and excellent touch for return of spiny serves. I use it on the backhand side of my Off- blade. Loops are very spiny, ball drops in every time. Very controllable.
IN HIGH HUMIDITY THIS RUBBER DOES NOT WORK! It gets slimy and the ball skids off, almost like anti-spin. Has anyone else seen this ? I'm not going to throw the rubber away, as it works fine in the winter months.
