The OS in TaylorMade’s new OS and OS CB putters stands for “oversize.” With its new putter line, the company took two of its most popular blade and mallet putters — the Daytona and Monte Carlo — and increased their size, which increased their forgiveness as well as the size of their alignment aids.

Clay Long, TaylorMade’s Director of Product Creation for Irons and Wedges, has been designing putters for a long time, most famously the MacGregor Response ZT 615 putter Jack Nicklaus used to win the 1986 Masters. That putter had an extremely high moment of inertia (MOI), a measure of forgiveness, thanks to its all-aluminum construction, which allowed the putter to be made bigger but gave it a non-traditional sound.

The OS and OS CB putters have a high MOI, but don’t skimp on feel thanks to their thin-wall, polymer-filled construction. The putters are cast from steel and then “skim milled,” which gives them a premium look and consistent shaping. After the milling process, polymer is injected into the putter bodies to dampen their sound, and the backs of the putters are then sealed with a red aluminum insert. The OS and OS CB putters also use a new TaylorMade 6061 aluminum face insert, which is vertically milled to create more friction at impact for a better ball roll.

According to Long, the OS Daytona putter is 7 percent larger than last year’s Ghost Tour Daytona. The OS Daytona CB, which stands for “counter balanced,” has a heavier head and heavier grip to help golfers make a smoother stroke. Its putter head measures 13 percent larger than last year’s Ghost Tour Daytona. The OS Monte Carlo is 5 percent larger than last year’s Ghost Tour model and 12 percent larger in the CB version.

The new line also includes a Spider OS putter, which is available in a standard and CB version that has a more square look than past Spider models from TaylorMade.

All six putters will be in stores March 18, and come stock with SuperStroke’s Mid Slim 2.0 grip (the CB versions use a 13.75-inch SuperStroke 2.0 XL grip). Learn more about each model below.
