The Butterfly Nakama S4 Ping Pong Racket is a hybrid of wood and carbon fiber layers. The wooden surface outer plies are followed by a thin layer of carbon fiber. The addition of the carbon fiber will make the blade lighter, stronger and stiffer. This provides a larger sweet spot than an all-wood blade and will therefore be more consistent. Wakaba is a well balanced mix of speed and spin which is ideal for an intermediate level racket. Not too fast, not too slow, just right. Wakaba offers good spin for a high control rubber. Speed - 72.5, Spin - 60, Control - 79.
