The Kastaplast Berg is a unique putt and approach disc with a curved indented flight plate. This thumb track allows the disc to rest comfortably in your hand and fly with increased consistency. The Berg is a slow flying putter that stays stable and never drifts too far away from the target.
This disc comes in a HARD version of Kastaplast's K3 plastic which is their base line plastic – grippy in all conditions. With this plastic you will get that nice worked in feel pretty quickly. Compared to other base plastics, K3 is medium soft.
