ULTRA LOW SPIN TOUR PERFORMANCE

91视频's squat, powerful, player's driver combines the scope to optimize launch and spin with the ball speed enhancements of 91视频's CORTECH Chamber. Two convergent weight tracks allow the ST-G to be anything from a low spin bomber, fade or draw biased or simply a more stable compact driver.
