The medium pips out rubber plays just like advertised. The rubber produces extremely low trajectory balls and is able to scrub off spin from looped balls. It is a great defensive rubber for those who like close to the table blocks. The rubber is able to generate enough spin to attack easily. It is considerably less spinny than 729 802, 802-40, 799 and slightly less spinny than 563. It has a taller and smoother nib with less density per square inch than 563, which to me is the closest medium pip to it. Loopers who play against it will hate playing you because of the large variance of flat and slightly spinny balls with low trajctory they will receive from it. Because of the low trajectory you have to remind yourself to hit "high", just the opposite of most short pips. If you plan to use inverted on the other side of the paddle, this is a difficult rubber to use since the throw angle differential between the two will be huge. I like playing with 388 C-1 with a thinner sponge, like .6 or 1.0 mm for the greatest control. It also plays very well with 1.5 mm sponge for more speed but less control and maybe less deception. It doesn't reverse like a long pip, but gives you more options on spin and quick attack.
