And that's what Mizuno want you to do. They took out the Scottish National Fitting Centre and rolled out these carts and their be all and end all swing DNA gizmo. The DNA thing can be manipulated as I have seen in action. The results can be so far wrong as per this thread that its incredible.
Its a dangerous tool and even more dangerous in the wrong hands. As a starting point I would even have my reservations about that as well.
On the other side of fence, which never gets the light of day, are the success stories of DNA. Many people have found the right shafts using this method, including me.
As I said earlier, Trackman or Flightscope can be just as, quote, 'dangerous' and it can be manipulated (via atmospheric inputs) or misleading (the fitting focusing on ball speed only). In the early days of going to fitters, some of the information, recommendations I got from fitters using these devices was laughable. As an example, a fitter focused on small aspects of the data, such as ball speed, saying "look, you are getting 3 mph more with this shaft/head, giving you more distance!". Great, but what about the 8000 rpm spin I'm now getting with the 6i? In fact, my distance has decreased as the ball is ballooning.
The last few years I've made a habit of going to fitters just to test their knowledge and use of technology. I can tell you, it's not pretty. Main culprits are those that use radar devices, as they are solely using ball speed to fit clients. Their ethos is higher ball speed must mean more distance and thus stiffer shaft, playing to the ego and getting the sale. Not great - what about tempo, spin, launch, dynamic loft and other defining factors?
Any fitting device, whether DNA, Trackman or GC2, can be manipulated to give any result.
