The Berg is unparalleled: A low glide putter that flies true every time, and will not outdrive the basket. Its aptitude lies in precise landings and eliminating the need for distance control. A distinctive attribute of this disc is its thumbtrack, with a lowered flight plate that almost hugs your hand. Remarkably versatile for both forehands and backhands, the Berg fearlessly accommodates the full extent of your power, steadfast against turnover, and adeptly managing even the most delicate approaches you encounter.

Consistency is a prized quality in disc golf, instilling confidence in players. The Kastsaplast 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.
