We only offer our optimized steel shafts in our irons and fairway woods. The design of our golf shafts in combination with our proprietary Shaft Optimization Process produces a perfectly balanced golf club (all other brands use stock shafts with no balance criteria whatsoever). Once this perfect balance is achieved the concept of shaft flex disappears and the golf club will perform at its peak performance level regardless of swing speed or strength. You can liken it to a precisely balanced bull whip where there is a perfect transfer of power along its length from the butt to the tip regardless of the strength of the person using it. Our golf clubs are played by professional golfers and long-drive champions with extremely high swing speeds and played by 70 and 80 year old senior golfers with very low swing speeds. In each case the golfer will realize their optimum trajectory, distance and control/accuracy. The results of our studies and testing over the past two decades have shown that our shafting method produces the highest level of performance for any golfer.
We are also the only golf club brand to perform shaft flex plane orientation (Spine Align/Puring) as part of our Shaft Optimization Process. If a golf club is shafted without regard to the inherent flex plane of the shaft it will try and rotate around its axis to a position of stability during the swing which creates an oscillation between shaft and club-head. This oscillation results in the club-head literally wobbling through impact. However, when the shaft is correctly oriented in respect to its inherent flex plane it will resist twisting to any other position when placed under load and will remain stable and on-line through impact. The feeling is that the club-head is riding on rails through the impact zone resulting in a much higher degree of ball striking consistency with a maximum transfer of power at impact.
