The FX-4 is a fast, understable fairway driver. It has a wider rim than other prodigy fairways, allowing it to carry more speed and distance. In flight, it will have neutral to slightly understable characteristics depending on your arm speed. Power players will see some movement to the right (right handed backhand), while lower arm speeds will get a straight ride with a mild finish.
The 400 series is a premium blend of material that is extremely durable. The unique blend of plastics feels as good as it looks and will be able to be broken in over time. This tour quality plastic gives the thrower better grip even when it is wet.
