The difference between the Phantom X5 and Phantom X5.5 is the hosel. The Phantom X 5 is fitted with mid-bend shaft technology, while the Scotty Cameron Phantom x 5.5 carries a small slant hosel. The Phantom X 5 produces a face-balanced design ideal for straight strokes, and the Scotty Cameron Phantom x 5.5 putter has an enhanced toe hang suited to arched strokes.
