I went to forward golf this week for a fitting. Was really cool. Their fitting system basically isolates 6 or 7 various variables in the swing - bounce/weight/kick point/swing weight/grip size/lie angle
to measure each one they give you 3 clubs with different variables. For example to measure club bounce they give you 3 clubs - low bounce medium bounce high bounce holding all other variables the same. You hit three to four balls with each club and using track man determine which bounce is right for you. You then move on to the next variable and repeat the same process. Once they determine all the variables based on your swing they give you recommendations for best club heads shafts and grips for you to use. They will build the clubs for you if you choose as well as purchase their club heads.
I am a numbers guy and I thought the fitting was very interesting and thought the fitter I was working with (Seth Gregory) was extremely knowledgeable. Highly recommend doing it in person if you are ever in LA.
