High MOI and head material change your strike feedback
The fitter explains that a very high-MOI driver head leaves you desensitized to where you strike it on the face and changes your ability to react. Head construction also shifts the feedback: a head with carbon (the Ping) gives a different acoustic and different vibrations, while an all-titanium head produces a higher pitch that makes you more aware of your strike location.
