Rockstar is a beginner friendly fairway driver from Active Line. Designed with the player in mind, this disc allows easy access to begin opening up your game to untapped distance and control. Golfers with more experience and power will find this disc to be moderately under stable and will display more high-speed turn from the flight. Beginner to intermediate level players are going to enjoy the smooth nature of it’s flight patterns, superb gliding ability, and adaptability to both forehand and backhand throws. Rockstar features a thin rounded nose with gentle wing on the underside of the disc, making for an extremely comfortable fit in your hand.
Discmania Active Premium plastic is the highest quality plastic in the Active Line. It is similar to Innova's Champion plastic. It is very durable and will hold strong on the course!
