So I finally saved up enough to upgrade my sticks. My current setup is: 913D2 8.5 Diamana 72g 904F 15 Fujikura Speeder 910H 19 Diamana Blue 4-5 712 AP1 Project X 6.5 6-PW 712 AP2 Project X 6.5 52-56-60 Vokey 200 Series Oilcan DG Spinners

I am getting fitted next weekend and am looking to upgrade to a TS driver and 3-wood, AP3 irons, and SM7 wedges. Obviously that may change depending on the fitters recommendation but it should be in that ball park. I have never been fitted before and the irons and wedges are both cut down to 1/2” short. I figured a little shorter would increase accuracy but I often question if it’s hurting me. The shafts are project X 6.5’s and I will admit they are pretty stiff. This is all a result of buying used off of eBay which I am done with. I feel like it will be a big jump in technology but also a nice jump with just the fitting alone. So my questions are 1) Can I expect noticeable results? I am currently at an 11 handicap. 2) If I should be playing standard clubs, will having played with the shorter clubs screwed up my swing to the point where my fitting results will be skewed?
