Kastaplast says this about the mold: “Reliability is one of the most treasured features for any disc golfer. A disc that behaves the same way no matter what conditions it is presented to, will always increase the players confidence on the course. The Berg X is such a disc. The characteristic of the original Berg is still there and the feel and flight is familiar… until you expose the Berg X for more power. Give it all you got, it doesn’t matter, the line will remain the same. The increased stability also makes it perfect for the forehand approach.”
