Kastaplast says this about the Vass: "Just as the late Grym, the Vass is made for long and smooth S-curves and tailwind bombs. It’s a workable big distance driver for the common player or a turnover hang glider for the bigger arms. The 22 mm rim combined with the smooth Kastaplast plastic guarantees a comfortable grip, and the sharp profile and fast flight will give you a cutting edge on the long fairways. The Vass is a great disc for shaping lines into the distance but stay away from the Common Reed."

| Forward Push |
| The initial thrust forward during the high-speed phase of flight |

It's a Grym but new
Nov 17, 2023
It seems to be a good replacement for the Grym in the Kasta lineup. The Vass is pretty true to numbers, I think sometimes disc golfers underestimate how hard you have to throw a 12 speed for it to do what it's supposed to.
Rip it over on a forehand and it will hold the line before fading out, Rip it flat and it will turn some for me but it will then go ahead and have a reliable fade.
The Vass has the same, ...

The Vass has the same, great Kastaplast feel. But, the one I purchased was more overstable than the numbers. It's more stable than my new Latitude 64 Grace. The reviews online suggested it was not that stable. Great disc, just a toss up on the flight numbers.
