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 350 is a unique blend of plastics designed to be used in several different models to get them into the 140-159g range. The high quality discs produced in this plastic have amazing glide and each model has its own unique flight characteristics. The 350 is a soft, grippy plastic that you will be able to break in over time. Although less expensive this exceptional plastic feels and flies great. The 350 stays grippy even in wet conditions.
