Boost your accuracy and improve your touch on the green with TaylorMade's Rossa Sienna right-handed men's putter. TaylorMade engineers created a heel-to-toe weighting system for the Rossa Sienna with an extremely high Moment of Inertia (MOI), boosting the putter's forgiveness, control, and accuracy on mis-hits. The putter is also outfitted with Anti-skid Groove System Insert+ (AGSI) technology, which incorporates 14 closely positioned, uniquely shaped grooves to help promote forward spin and reduce skid and bounce. Whereas a typical putter produces backspin at impact--which makes the ball skid and bounce before the forward roll begins, thus producing an unpredictable line--the AGSI+ system is engineered to produce forward spin immediately, helping keep the ball on line from the start. Good forward spin also increases distance control, so you don't come up short unexpectedly. Like all other Rossa face inserts, the AGSI+ is made of Titallium, a seven-metal alloy that's 40 percent lighte | The TaylorMade r7 XD iron set features the following: A Tuned Performance Cartridge distributes weight to the perimeter of the club head for increased forgiveness on off-center hits 100% CNC-milled, thin, 6-4 titanium club face material increases C ...
