Re: Aldila NV versus Aldila VS Proto by youSure, they make a VS Proto for drivers -- I have one in my Maltby CT250 driver I just built this past month. It plays great and in my opinion is a much much better shaft than the NV or even NVS.
It is a pricey shaft though, it retails for about $180. I picked up a mint quality professional "pull" from a factory Bridegestone driver on ebay for about $50. It even had a brand new Bridgestone branded GP Tour Velvet grip on it (which is what I play anyway) so that was a plus. Great shaft, especially at that price.
