Rossa TP (Tour Preferred) putter line is the product of collaboration between Rossa putter engineers and a variety of tour professionals that resulted in the fine-tuning of six existing Rossa putter models. This fine-tuning includes subtle changes and refinements that succeed in making the Rossa TP line of putters look, feel and perform in ways that tour pros prefer. Rossa TP putters are constructed of 1020 carbon steel and are 100 percent precision-milled with strict attention to detail, and "tour-shaped" to reshape and size things like blade lengths, width and the top line. Each Rossa TP putter incorporates TaylorMade's famous dual Titallium insert technology used in the Rossa putters, one in the clubface, one in the back of the putterhead, permitting the reallocation of 35 grams of weight to strategic areas of the putterhead, increasing the head's moment of moment of inertia (MOI) for increased stability. In addition, the clubface insert delivers an extraordinary soft-yet-crisp feel at impact that's unparalleled. All feature TaylorMade's striking TP logo, identifiable by its dual racing flags, on the sole.
