Top golfers know that one of the keys to good putting is eliminating wrist movement and instead using the larger muscles of the back and shoulders while making the stroke. That is the surest way to produce consistent speed and direction – and to make more putts. Question is, how best to ensure that kind of action? The people at SuperStroke believe their putter grips are the answer, thanks largely to the so-called parallel technology they employ. Unlike traditional grips, which taper from butt to tip, these products are the same size top to bottom. According to Jon Luna, marketing director for SuperStroke, that allows golfers to apply equal grip pressure and alleviate tension in the hands, so players are more inclined to use their larger muscles when they putt.
