The new HZRDUS Silver line is now offered in a hybrid/iron profile. Utilizing a new Dual Torsional Design throughout the shaft, HZRDUS Silver Gen 4 is available in lighter weights with a stable yet playable profile to best suit a wide variety of golfer. Dual Torsional Design is a proprietary process that allows our engineers more freedom when designing a golf shaft—allowing them to dial in stability and desired torques more efficiently, producing a fully optimized golf shaft with regards to player profile.
