Discmania's P2 is one of the most popular putters from Discmania, and it has been used by many of the best players in the world over time. P2 is a relatively deep putter and it comes without the small bead on the underside. It is designed to fly straight, and at the same time it can withstand a lot of force if it is thrown from the tee or used for approaches.
In the Flex 1 version of the D-Line plastic, you get a slightly softer disc with a little more grip than you will experience in Flex 2 and Flex 3.
