Discmania's Hard Exo plastic is a blend that offers a balance of grip, durability, and stability. It is firmer than their baseline Pro-D plastic, but not quite as stiff as their premium plastics like C-Line or S-Line. This makes it a good choice for players who want a disc that will grip well in most weather conditions but is also durable enough to handle some abuse.

Here are some key characteristics of Hard Exo plastic:

Grip: It has a soft, velvety feel that provides good grip in both dry and wet conditions.

Durability: It is more durable than Pro-D plastic, but not as durable as C-Line or S-Line. It will show wear faster than some other premium plastics, especially if you hit a lot of trees.

Stability: It is more stable than Pro-D plastic, but not as stable as C-Line or S-Line. This means that it will hold its line better in the wind, but it may not turn as much as you want it to.

Feel: It has a slightly tacky feel that some players prefer, while others may find it to be too grippy.

Hard Exo plastic is a good choice for players who are looking for a versatile disc that offers a good balance of grip, durability, and stability. It is a good option for both beginners and experienced players alike.
