NEW for 2019! The first-ever Studio Stock 28 Slot Back was designed to offer an impressive crossover between blade and mini-mallet. Robert Bettinardi worked with his PGA Tour staff to refine his popular SS28 model by finely milling a slot in the rear flange in order to frame the ball perfectly and allow for maximum forgiveness at impact. The SS28 SB was engineered with a center shaft, adding to the square profile with greater perimeter weighting and higher MOI characteristics. With feedback from major champions, Robert Bettinardi milled his F.I.T. Face 20% deeper for an even softer feel at impact. A stunning hand-polished platinum finish gives the SS28SB Center Shaft putter a durable and clean appearance, sure to inspire confidence on the greens!
