Nippon shafts are very good shafts as good as DG or PX in many many cases, however when it comes to a shaft in my opinion it’s more of a personal feel and expectation of result, not just a swing speed for this flex etc etc.

It’s amazing how many people genuinely play the wrong shaft specs either that be weight or flex. To fully know your best off going to see a fitter or a centre that will let you try the product on a range.
