The E-Series is a large mallet, so the head twists less when you miss toward the toe or heel.

Your hands aren't in exactly the same place on every putt. The curved face helps keep your loft at impact steady when they move, so your putts roll a more consistent distance. That's what makes it a forgiving putter. You can adjust the shaft position, lie, length and weight to fit your stroke. Shaft options include center shaft and zero torque.
