The Viking Discs Rune is a low profile putt and approach disc with a perfectly straight flight. This putter is beaded, which helps it maintain stability with wear over time. The Rune is great for putting and has an easy to predict flight path. A straight flight with a slight fade at the end, this makes for a great straight disc golf putter. Storm plastic is Viking’s premium plastic, with great durability and grip, also it is a clear plastic. If you don’t like the storm plastic, try the Rune in another plastic, Ground, or Armor.
