The Discraft Pro-D Buzzz is a straight flying midrange driver with a stability of 0.0 (stable). In comparison, the other types of Buzzzz have a stability of 0.5 (stable/slightly overstable). It has quickly become one of the most popular discs of all time. This workhorse is the disc golf disc that you'll reach for again and again. Throw it hard and the Buzzz will hold any line you put it on.
Pro-D plastic is the least expensive. It's great for beginners as entry level discs and pros love them too when they get 'beat up' and 'broken in'. It offers superior grip and comes in a rainbow of colors.
