Vass is a replacement for the Grym that Kastaplast discontinued.  The Vass has a long smooth s-curves when thrown on a hyzer angle with just the right amount of power the disc will still come back nicely with a reasonable fade at the end of the flight.  A distance driver with a clean shape and a comfortable 2,2 cm rim. This disc is a big D driver for the common player. Thrown flat this disc comes down quickly and could work very nicely for those needed longer turnover shots..
