Stock shafts are Dynamic Gold S200 shafts. They just have vokey shaft labels.

If you will look on their site it will list their stock shafts. Their are about three shafts that are stock when ordering clubs from their site including those above. Project X and Nippon included. I got a stock Nippon shaft S300 at a Vokey event a Pinehurst with Mr Vokey and Aaron Dill. Guess if you purchase from a retail store the DC shafts most like would be what you would get.
