Since its inception over 40 years ago, Sriver has proven itself at every level of competition. Perfect for the allround attacker, Sriver EL has a harder rubber top sheet, making it capable of good spin while still maintaining control. Also, the medium sponge lends itself to controlled attacks and blocks, yet it is a good balance of the power of original Sriver and the touch of Sriver FX. For allround players, developing attackers, and those seeking a good balanced rubber, you can't get any better than Butterfly Sriver EL! Surface: Inverted Speed: 10.0 Spin: 8.0 Density: 35 To get the most out of your rubber, it is recommended that you clean it after each use and store it properly. Using our Racket Care Kit, use one pump of the Spin Refresh on each side of inverted rubber, then use the Rubber Care Sponge to thoroughly clean it. Once it is dry, apply your protective sheets and then place it in your case. Ideally, store your paddle in a climate-controlled space and avoid extreme temperatures for extended periods of time.
