Are Nippon Shafts “step” models or 1 piece like Rifles ?
Hi Mark, If you have lost some distance with your current shaft model- the trouble might be with the weight of the shaft, or the flex of the shaft. Since you are currently using Mizuno irons, you might consider connecting with a Mizuno center that offers their new “optimizer” kit, which has a variety of shafts and heads for instant side-by-side comparison via the use of a quick connect interchange head and shaft system. I like this type of system, or any Opti-Fit, Select-Fit, or clubmaker fit system that allows for live, comparative, side-by-side testing so as to identify the ideal flex, length and shaft model. Using this approach gives you all of you answers. Many of the Rifles models have a straight taper, no step shaft design. Our Nippon Shaft models have a stepped design. Both are premium shaft contruction types.
