The P1 is easy to learn and easy to throw. Awesome disc both for putting and approaches. Great for touch shots especially when broken in a bit.
It has a very neutral and glidey flight, so it is also good for learning clean form. When you learn to drive with this putter, it will teach you a lot about your throw. The straight flight pattern also makes putting a joy.
If you are unsure which putter to choose, you cannot go wrong with the P1.
Good for: Putting, approaches, for beginners, advanced and pro players alike.
