The Midari is the midrange disc in the Prodiscus line. This stable flyer has a great feel and goes where you want it to go. It is a fairly slow flyer for a midrange, but flies straight, with a sharp end-of-flight fade. The Prodiscus Midari is available in two plastics. The basic blend is soft and very grippy, while the premium blend is more durable. Midari’s in Premium plastic tend to be more overstable.
Ultrium is the ultra-premium Prodiscus blend. This unique plastic has an incredible feel and impressive durability. Ultrium plastic can be compared with Prodigy 400G and has been described as having the tackiness of GStar but the flexibility of Innova Star plastic.
