The A4 is next in the lineage of the Prodigy "Approach" series. We are still waiting on description of flight characterisics, but it looks as if the A4 will be the straightest flying of the "A" series to date. The A4 does feature a truly unique "notched" rim, unlike any other disc currently on the market.
The 300 Series is a special blend of materials that is durable enough to take solid impact but has the ability to be broken in over time. The 300 series has been developed for optimum feel and grip for Putters and Mid Range discs.
