I have just purchased a set of 718 AP2 Irons (3-PW) with AMT TOUR WHITE S300 shafts from my local pro shop. Played 2 rounds with them and just cannot get used to the feel of the Stiff shafts, as I’ve always used Extra Stiff (Previously Rifle 6.5’s). Do Titleist offer a shaft replacement service that would save me the embarrassment (and cost) of going back to my pro shop and asking for Extra Stiff shaft options? Thanks
