To answer your question there are all different kinds of club fitters, meaning that there are ones that really take their time and use high end equipment like a trackman monitor for your numbers when hitting a golf ball with irons and woods...etc.. Then you have top notch golf fitters that are more knowledged then others, letting them know your preferences in feel and stuff of that manner is good to help gear them towards certain shafts or clubs you may be interested in and as far as flexes that will be left up to the numbers on a monitor if your getting a full out fitting. For example I am 6'3 170lbs and play +1/2 inch over standard length shafts in all my clubs except for drivers and woods, and I have my irons at 2 degrees upright from standard. That does not mean everyone my size needs them specs because wrist to floor length and other stuff comes into play but general rule of thumb is a guy my size plays specs around there! If at any time you feel like your hitting a club you dont like they directed you towards or trying a shaft that doesnt feel good , then just let them know! It's in their duties to properly match what you need for Length and lie and flex and shaft ideas for you but it all comes down to what clubs you want to go ahead and purchase based on feel after they fit you for your specs! Where your going are pretty solid people, I do not live in the area nor have been to their store but have done business with them before and they are extremely nice, also it wont cost you over 500 dollars to get fit like it would going for a set of clubs at a titleist fitting center! Good Luck!
