Yes i4-Tech Callie Putter
The Yes! i4-TECH putters include different models to fit any putting stroke type. All of these putters have a rich PVD finish for a great look. But the Callie, Rachel and Stephanie putters are each more than just a pretty face: the C-grooves, tungsten weighting and thermoplastic polyurethane insert behind the face of each putter result in exceptional feel and performance. The Callie and Rachel putters have traditional blade heads and are suited for players with varying degrees of arc in their putting stroke, while the Stephanie is a mallet putter with perimeter weighting to boost Moment of Inertia for straight-back, straight-through type strokes.
