I would contact the fitter and see what shafts he/she has available. If they are employed by Titleist and they are doing the fittings at local clubs, most likely are standard shafts. We on here are Titleist loyalists just like you and are would not have knowledge of that information. Best of luck at the fitting.

Depends on where you do the fitting as to how many additional shafts they have in their fitting kit. All will have more than just the standard offering but places like TPI will have every option imaginable.

They should have pretty much all the shaft options available.
