Callaway SR-1, SR-2 and SR-3 golf balls
If a golfer doesn’t have the swing speed of a tour pro, are they really going to get the most out of a tour-level golf ball?
According to Dave Bartels, senior director of R&D for Callaway golf balls, the answer is likely no, which is why Callaway’s new Speed Regime line of golf balls have three different constructions to suit golfers with different swing speeds.
The SR-1 is designed to work best for golfers with driver swing speeds of 90 mph or less. Like Callaway’s premium golf balls of the past, it uses the company’s dual-core construction and a thin mantle layer that allow the balls to launch with less spin off longer clubs and more spin off shorter clubs. But the four-piece ball has a new HEX aerodynamic pattern that helps golfers achieve a higher trajectory for more carry distance.
The SR-2 will work best for golfers with driver swing speeds between 90-and-105 mph. Its HEX dimple pattern is balanced to reduce drag at the high-speed portion of a ball’s flight, such as the first third of a driver’s flight. But it also adds lift during the last third of flight, when a golf ball is traveling with less speed. The five-piece golf ball also has an additional mantle layer that helps boost ball speed and reduce spin for better performance with longer clubs.
The SR-3, which targets golfers with driver swing speeds of 105 mph or more, will be the 2014 Callaway ball of choice for the company’s tour players. Its HEX dimple pattern is designed to reduce the drag forces that rob high-speed golfers of distance and accuracy.
Like the SR-2, the SR-3 is a five-piece golf ball. The most important layer of the ball is likely its outer mantle, according to Greg Sabella, director of marketing for Callaway Golf balls, because of its impact on feel. In the past, Callaway has been criticized for the firm feel of its premium golf balls, such as the 2013 HEX Tour Black. But the SR-3′s much softer ionomer outer mantle makes it feel noticeably softer than previous models, Sabella said.
Each of the Speed Regime golf balls have a thermoplastic urethane “Duraspin” cover that is specially formulated to accommodate the three different HEX dimple patterns. They will be available in January and sell for $47.99 per dozen.
