PHD

The Schidtt PHD is just Schidtt piled higher and deeper. The PHD is designed to promote the maximum illusion that you can pound  300 yard bombs, hit darts from the fairways with maximum precision and provide back spin on all your short irons if you tee this baby up. With 4 layers including a soft outer core and the highest price tag you might be able to knock some strokes off your game.
