The Protype Tour Series #9 is a Toe-weighted, heel-shafted, flanged blade with a long hosel and half-shaft offset. It is made of 1025 carbon steel, which provides premium feel, and the face has a deeper, sharper milling pattern to increase friction for better feel, truer roll, and more consistency. Using the headweight optimization, the putter head weight is matched up with the correct shaft length, the shorter the shaft the heavier the head is.
Like all the Odyssey products, this one does not disappoint. It's more expensive than other brands, but what you get is a good solid all around putters.
