The A5 is a shallow rim, slightly overstable approach disc. The A5 is closest in feel to the Distortion, but will fly straighter with less fade as you break it in.
500 Plastic
500 Plastic is a premium blend that has a less gummy feel than 400 plastic. This provides you with an extremely confident grip and a stiffer flight plate, balancing just the right amount of flex and firmness. 500 Plastic has a uniquely pearlescent finish which adds another visual element to each disc.
