This is the shit I straight up rebel against. The guy at CC fit me into an iron shaft that was definitely better than the DGs I'm playing now, but it wasn't $90 per shaft, extra, better. Combine that with them recommending a house iron that they were clearly getting kickbacks on at ~$200/head, and it's loony tunes. I'm a recreational golfer, and a damn good one, and there's no value equation in the world where I need ~$1000 in SHAFTS ALONE, just for my irons, and topping $300 a club. If you aren't trying to win money playing this game, find a head and stock shaft combination that you like, and just go play. You aren't handicapping yourself because you don't have tour-issue KBS Tour 130s, or whatever. Spend that money on lessons. Get fit for driver and fairway woods, and then buy the damn shafts on eBay. PgaTour superstore can change the shaft adapters for you for ~$40.
Oh, PUREing shafts is absolute bunk as well.
Edit - this sounds a little more angry than I'd intended. I thoroughly enjoyed the fitting process. But I looked at it as making sure I wasn't missing some major technological leap, not trying to eke out 5 more yards on the 7i. What I learned is that the irons I had fit me really well, and I could get new irons with similar loft/lie specs on ebay for ~$750, which is what I did. The guy was super nice, and didn't pressure me to buy, but you have to know they're going to try and make it VERY easy for you to drop $2k with them before you leave your fitting. Just know that going in - they don't make much money fitting clubs for $250 / 3hours. They make money selling clubs, especially premium shafts; that's the motivation. FWIW, I have confirmation direct from a club engineer at a top-5 club mfr that the "Tour Issue" DGS400 shafts that I play aren't special. They literally roll Dynamic Gold steel shafts off the manufacturing line, and the heavier ones get slapped with the S400 shaft label. Because they're at the high end of the weight spectrum, they tend to cluster closer together in weight; thus, they're advertised as "tighter quality control." But that's a result of the physics, not some special mfg process. Other shafts are the same, I have to assume.
