TG rating 
The computer-milled head of the Guerin Rife Aussie is made of 303 stainless steel and has Rife horizontal grooves that are four-hundredths of an inch wide to reduce the area of face contact by two-thirds, helping minimise sidespin on off-center hits.
"I like the look over the golf ball, and the grip fits snugly in my hands."
It lacks the geek factor of the popular two-bar putters, but not the groovy face technology. Get it groovy....
