The Sacks Parente Golf Series 91 putting instrument was inspired by the iconic putter shape that is a favorite of PGA Tour Champions Tour player Ken Duke’s favorite putters.

The SPG Series 91 ($349.99) features a classic style with a clean, minimalist look favored by golfers of all skill levels.

This putter might look classic, but that’s where the history ends. Lots of performance technology in a classic design, as Sacks Parente adds the cutting-edge performance enhancing technologies that the company says makes this “a superior putting instrument.” Anyone who has played with an SPG putter knows what that means. The Series 91 features three performance technologies: a patented Ultra-Low Balance Point technology, a Weight-Forward Center-of -Gravity (CG) design, and high MOI.

The high quality milled 303 stainless steel, according to the company, provides a soft responsive feel at impact. The patented Ultra-Low Balance Point (U.L.B.P.) creates a smooth putting stroke that naturally squares at impact without the need to manipulate the putter head.

On an off-center hit, the company says, the Weight-Forward CG provides a consistent roll and reduces skidding to make sure your ball gets to the cup.

The SPG Series 91 “Duke” is fitted with 50 grams of tungsten in both the toe and the heel and all towards the front of the head.  An astounding 77% of the head weight is in the heel and toe.  The MOI of this head is almost 5000 – unheard of for this iconic shape – and ensures that there is very little energy loss or face deflection on off-center hits.
