The TaylorMade Rossa Classic Monte Carlo 7 putter incorporates an improved version of Rossa's famous Anti-skid Groove System Insert (AGSI), called AGSI+. What makes AGSI+ superior to the original is the addition of two grooves, which raises the total to 14 from 12 and which brings the grooves 22% closer together. That brings more grooves into contact with the ball more often, allowing AGSI+ to more efficiently negate backspin and promote forward spin at impact, equalling smoother roll and helping the player make more putts. Additionally, the bright red AGSI+ insert is highlighted in gold, lending an elegant look. The TaylorMade Rossa Classic Monte Carlo 7 is constructed of soft 304 stainless steel enveloped in an opulent Midnight Black finish.

The composition and construction of the AGSI+ insert together bring the grooves into direct and active contact with the ball during impact, even on short putts. First, Titallium is a low modulus alloy, meaning that it's more flexible than steel. Second, the grooves in the face serve in part to strategically soften the insert's structure. Together, these factors allow the insert to deform at impact, which puts the AGSI+ grooves into direct contact with the cover of the ball. With more grooves positioned closer together, AGSI+ puts either six or seven grooves into contact with the ball on a typical 40-foot putt, depending on the type of ball, the putter's loft, and whether the ball's equator is in line with a groove or a landing space between the grooves. On a five-foot putt, two to three grooves come into contact with the ball. In either case, the behaviour of the ball at, and right after, impact is affected more by AGSI+ grooves than by other types of putter face inserts either hard or soft. AGSI+ grooves, because of their unique shape, "hold" the ball at impact, reducing backspin and promoting forward spin. The result is less skid and bounce, equalling better distance control and better directional accuracy.
