Unique New Putter Specially Designed with Input
from Putting Master Dave Stockton
CARLSBAD, Calif. (April 26, 2010) – TaylorMade Golf, maker of Rossa® putters, has unveiled Corza Ghost, a mallet specially designed to be exceptionally easy to aim, and exceptionally easy to use to roll the ball down your intended line. It was designed with significant input from the hottest putting instructor in the world, Rossa Tour Staff professional Dave Stockton.
"We started with the intention of designing a putter that's easier to aim than any other," said Bill Price, Rossa senior director. "That led us to experiment with a white finish. We consulted Dr. Steven A. Hitzeman, a professor at the Indiana School of Optometry and he felt we were onto something."
The Contrast of White Against Dark Makes Aiming Easier "Corza Ghost's white putterhead stands out so clearly against its background — the putting surface – because of the high contrast between white and green," said Dr. Hitzeman, who is also a past president of the Indiana Optometric Association and a past chairman of the American Optometric Association's Sports Vision Section. "That high contrast maximizes stimulation to the retina and highlights the head's shape and features. The contrast would be lower if the putter were black or gray because these colors are closer in luminance to the color of the putting green than white. White creates the biggest difference in luminance, hence maximizing contrast and promoting focus. Many golfers use the leading edge of the putter as part of their alignment strategy (by positioning the edge perpendicular to the imagined target line). So, this high contrast for the leading edge gives the golfer the best chance of squaring up the putterface at address. Also, the lines on the top of the putter are painted black to achieve maximum contrast against the white surface of the putter. All of these high-contrast alignment elements give the golfer the best possible chance of accurately aiming the putter."
To make it even easier to aim the Corza Ghost, Rossa engineers put three black alignment lines on the crown and a circular hole in the back of the putterhead, giving you different options to focus on to lock in your aim. "You can focus on the topline to aim Ghost," said Bret Wahl, senior director of iron, wedge and putter development, "or you can focus on the alignment lines to visually connect the circular hole and your ball to lock in your aim. The point is that you've got options, each one highly effective."
Because Corza Ghost's putterhead is white, its three alignment options are easier to focus on and use, according to Dr. Hitzeman. "The Corza Ghost putter's three alignment elements all have high contrast against their backgrounds. This high contrast maximizes stimulation to the retina, which helps the golfer to focus and use these aiming features effectively."
Eliminating "Hot Spots"
"Hot Spots" are reflections of direct sunlight from the top of the putter into the golfer’s eye, and distract the player's attention from the task at hand, which is to focus on the putterhead, the alignment system, and aiming the putter squarely down the target-line.
"When I started playing on tour in the 1960s, I used a silver mallet," said Stockton. "Nicks and marks would form on the crown from normal use. They lit up when sunlight hit them at address, which I found extremely distracting, so much that I would have the crown sandblasted frequently to erase the hot spots. Because when you look down at the putter you don't want anything disturbing your focus, which should be on the putterhead and the features of it that you use to align the putterface squarely down the target-line."
The Corza Ghost's white finish helps keep hot spots from standing out, allowing you to focus your attention on seeing the whole form of the putterhead and the alignment system, so you can aim without distraction.
Large, Solid-Feeling, High-MOI Mallet
Being a mallet, Corza Ghost's high-MOI head is extremely stable on off-center hits and feels extremely solid at impact. Its three alignment lines on the crown function not only to help aim the face accurately, but also to frame the ball in the middle of the face, which promotes solid, center-face contact on every stroke.
AGSI®+ to Promote Better Roll
Corza Ghost also has the advantage of Rossa's renowned and tour-proven AGSI®+ (Anti-skid Groove System Insert) Technology. AGSI+ features 14 polymer-filled grooves in the face that "hold" the ball briefly at impact to promote forwardspin for a smoother roll and more accurate results. The AGSI+ insert, in concert with the putterhead's extremely high MOI, also delivers superior consistency in forward roll on off-center hits, something not shown in tests of other popular putters.
Two More Ghost Models in the Pipeline
Corza Ghost is scheduled to appear at retail starting in June, at a manufacturer's suggested retail price of $159. Two more Ghost models – a blade and a mid-mallet – also with white finish and black alignment lines, are scheduled to become available in July.
