The Bettinardi Inovai 3.0 Heel Shafted Counter Balance Putter is Bettinardi's latest innovational masterpiece. This unique design is made up of both aluminum and stainless steel. The aluminum is utilized in the face to create our softest feeling putter yet and the stainless steel back weight creates the density needed for perfect head weight. This rare slight toe hang MOI mallet has extreme perimeter weighting which promotes a stable stroke and larger sweet spot. The counterbalance head promotes a smoother stroke with 50 grams of material added to the head, with another 50 grams added into the butt end of the grip and shaft.
