How did Rossa arrive at the name Corza for the new Monza model?
Corza was derived from the word "corsa," which is Italian for "race."
Does the Corza's wire-frame putterhead construction offer a performance benefit?
Corza's wire-frame putterhead construction allows Rossa engineers to move additional weight from the center of the head to the perimeter, improving MOI for greater forgiveness, equaling better distance control and accuracy on mis-hits.
Why is Corza's putterface described as "semi-floating?"
Corza's putterface is attached to the wire-frame putterhead in only three places - at the toe, the heel, and in the middle. Because of that, it appears to almost "float," which is why Rossa engineers refer to it as "semi-floating." The advantage of Corza's semi-floating face is that it delivers the kind of soft-yet-crisp feel at impact that's preferred by many players.
What purpose does Corza's Movable Weight Technology serve?
Corza's Movable Weight Technology, which employs the same TLC cartridges used in TaylorMade products with TaylorMade Launch Control, gives the player the ability to change the weight and feel of the Corza by installing differently weighted cartridges in two ports located in the rear of the putterhead. The amount of weight that can be installed in the Corza ranges from four grams (two 2-gram TLC cartridges) to 28 grams (two 14-gram cartridges). Additional TLC cartridges can be purchased separately.
Does the Corza employ a linear alignment system similar to that used in previous Monza models?
Yes, like the original Monza and the Monza Mid, the Corza features a linear alignment system consisting of an eye-pleasing bar bridging the front of the putter with the back; bisecting that bar is a vivid line positioned perpendicular to the center of the putterface. Corza's linear alignment system makes it easy to aim the putterface, enhancing confidence and accuracy.
Is there more than one version of the Corza available?
Three Corzas are available: the Corza, which is heel-shafted and features a double-bend shaft; the Corza 1, which is heel-shafted with an L-neck to create a toe-down option; and the Corza Center, which is center-shafted.
What is Rossa's Anti-skid Groove System Insert (AGSI) engineered to do?
A typical putter produces backspin at impact, which makes the ball skid and bounce before forward roll begins. That skidding and bouncing can rock the ball off-line to the left or right, and can cause the putt to come up short of the intended target. Rossa's new Anti-skid Groove System Insert is engineered to reduce backspin and promote forwardspin earlier in the shot.
How do skid and bounce affect a putt?
The unpredictable nature of skid and bounce can easily throw your ball off of your intended line. Skid can rock the ball to the left or right. Bounce steals momentum, so the ball rolls shorter than intended. In a game where fractions of an inch can make the difference between missing a putt or making it, skid and bounce can and do affect the outcome of putts. Additionally, inconsistent degrees of backspin off the putter, when combined with the imperfect nature of most greens, further compound problems with distance control. Reducing skid and bounce, which Rossa's AGSI is designed to do, promotes better distance control.
What is the makeup of the Anti-skid Groove System Insert?
Like all other Rossa face inserts, the AGSI is made of Titallium, a seven-metal alloy that's 40% lighter than steel, yet extremely durable. Rossa uses Titallium as an insert material because it allows Rossa engineers to save weight in the middle of the clubface and redistribute it to other areas of the clubhead, to improve the moment of inertia (MOI) for greater forgiveness on mis-hits and to move the center of gravity (CG) lower and deeper in the clubhead, to improve launch conditions to promote a better roll.
How many AGSI grooves are there, and how are they sized and positioned relative to standard grooves?
Rossa's Anti-skid Groove System Insert is scored with 12 CNC-milled grooves. Compared to standard iron or wedge grooves, AGSI grooves are 66% narrower and positioned 50% closer together.
What are AGSI grooves filled with?
Unlike standard grooves, which are typically empty, AGSI grooves are filled with a soft polymer which dampens unwanted vibration at impact, contributing to better feel.
How do AGSI grooves affect the ball, given the relatively low rate of clubhead speed for even long putts?
The composition and construction of the Anti-skid Groove System Insert work together to 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.
How many AGSI grooves come into contact with the ball on long and short putts?
Up to five grooves come into contact with the ball on a typical 40-foot putt. On a five-foot putt, about two grooves make contact with the ball. In either case, the behavior of the ball at and right after impact is affected more by AGSI grooves than by other types of putterface inserts either hard or soft.
How does the Anti-skid Groove System Insert reduce skid and bounce?
The grooves, because of their unique shape, "hold" the ball at impact, reducing backspin and promoting forwardspin. The result is less skid and bounce, equaling better distance control and better directional accuracy.
Does the Anti-skid Groove System Insert conform to USGA standards?
Yes - the amount that the AGSI deforms at impact is well within the USGA's standards. In fact, most polymer putterface inserts deform more than the Anti-skid Groove System Insert.
