Consistency is a prized quality in disc golf, instilling confidence in players. The Kastaplast Berg X epitomizes such dependability. Retaining the core traits of the original Berg in terms of feel and flight, the Berg X shines when given more power. No matter how much you put into it, the flight path remains unwavering, making it an ideal choice for forehand approaches.

Compared to the Berg, the Berg X will have more torque-resistance and a more prominent fade.

Kastaplast K1 is a unique plastic blend manufactured in Sweden. This disc plastic has an excellent feel. It is moderately grippy, but not sticky and is extremely durable. K1 plastic has a similar feel to Prodigy 400G or Prodiscus. K1 is a stiffer blend than Kastaplast's K2 plastic.
