ANDRO BACKSIDE D / DRIVE. This is a great and updated alternative to the long established Tackiness Drive. The surface has exceptional gripping ability due to the very pliable rubber composition. The high frictional surface is versatile for picking up the ball but also chopping with heavy backspin. The 40° sponge provides a nice catapult effect combined with superb overall control. If you play controlled top spinning use the 2.1mm. A multi stroke and variable allround game will suit the 1.9mm.
Please note: Backside D does not have the D indicated on the rubber top sheet. To distinguish it from the Backside C version you will note that it has ORANGE sponge.
All brands/manufactures tend to just change the sponge type/density for attack/defensive types of rubbers but still use the identical rubber top sheet.
