Discraft fairway drivers come in a variety of molds and plastics. Discraft uses a stability rating that is unique to Discraft, but it is basically a “turn” rating of stability — overstable (+3,+2,+1), stable (0), understable (-1,-2,-3). They also add in decimal points to their stability ratings which is a little different from the other manufacturers. All disc manufacturers have their own unique numbers, so often times a speed rating of 10 from one company, doesn’t necessarily match a speed rating of 10 from another company.
