The AviarX3 is an overstable putt-and-approach disc. This is Innova's most overstable Aviar model to date. The AviarX3 is ideal for headwind upshots and drives. AviarX3 is extremely torque-resistant. It has more high-speed stability than its buddy, the Aviar3. 
 
DX is an inexpensive, basic plastic. It has good grip, but wears more easily than premium plastics.
