The Scotty Cameron Select Fastback and Squareback mid-mallet models were designed with a combination of lightweight 6061 aircraft grade aluminum inlays and heavier stainless steel components to produce higher MOI and offer greater forgiveness. By mixing materials Scotty was able to increase the sweet spot, tune sound and feel, as well as incorporate four-way sole balancing into each model. #scottycameron #titleist #theartofputting #putting #golf #instagolf
