Grym X

Kastaplast says this about the Grym X:

THE X-VERSION OF GRYM IS DESIGNED TO BE THE SOLID MAIN DRIVER THAT EXPERIENCED PLAYERS ARE ASKING FOR, TO PERFORM THE DISTANCE DUTIES TIME AFTER TIME.
Grym X provides a well-balanced combination of speed, accuracy and glide. With a rim width of 22 mm, it fits right into the spot where the disc is workable and easy to grip, while still being very fast. Grym is Swedish for cruel or awesome, and the X stands for Xtra stability.
