I would be surprised if he ever would have fit into 7.0 shafts using normal fitting parameters.To add to this, I recently saw a WITB for Rocco Mediate and he is gaming super heavy 7.0 shafts in his irons. He said they are certainly too stiff for him so to speak, but that they work well for him and its where his comfort lies. So although there are generally accepted practices on weight and flex, it is up to ourselves to make our own determination as to what is best for our game. At Rocco's age and speed, I'm guessing not a single fitter would fit him into heavy 7.0 shafts.
