As with any golf swing the clubs need to fit each person individually for impact. If you are switching from conventional golf to Setup 4 Impact and keep the same distance from the ball at address. The clubs will fit you the same at impact as the impact plane angle will be the same as before. So if your clubs fit you before they will still fit for the Setup 4 Impact golf swing if you setup the same distance away from the ball. Many people do prefer slightly thicker golf grips than with conventional golf and I have recommendations for that.
