Center of gravity is a big topic with metalwoods and irons, but it's no less important with putters, especially mallets. A low CG can produce less backward rotation on the ball as it leaves the clubface, reducing skid.
Ping's new Ketsch putter has a wide soleplate made of stainless steel, which is heavier than the aluminum body, to lower the CG. The top of the putter has two alignment features -- a center line that extends from front to back and ball-framing lines at the heel and toe. The club also has variable-depth grooves on its face to maintain distance consistency on off-center hits.
The Ketsch name comes from the town where Ping's German office is located, but the putters are machined at Ping's Phoenix headquarters. The putter will be available in late March with a retail price of $220.
