Seeing as I have never had a fitting and my driver is seemingly producing unreal spin rates, I decided to go to Golf Galaxy and go get fitted for a new driver shaft. I expected to go in, hit some balls with some different shafts, see which one worked best, and leave with just a new shaft, but I ended up spending much more time and facing a harsh reality; something that may not be such a bad thing.
I got there and the fitter, Bobby, greeted me and had me hit a few shots with my 8 iron to warm up. The first shot was a bit off the toe and chunky and carried about 140 yards; 25-30 yards shorter than I usually hit an 8 iron. After a few more swings, I started hitting shots that were going about 165-168 yards. Nothing out of the ordinary, no "power boost" that some people say that GG has in its launch monitors.
Bobby then had me hit 5 drives with my driver. I averaged about 280 yards with a 115 mph swing speed and 3500 rpms of backspin, which even I knew was WAY too high. He instantly told me I shouldn't be hitting a stiff shaft in my driver, and that my swing and ball speeds put me almost to a 2x-stiff shaft. But he also said that my driver head (I have a Callaway RAZR Fit) wasn't doing me any good at all, and no matter what shaft I put in it I'd still have too much spin. To prove it he had me hit the Callaway Big Bertha with an x-stiff shaft in it. I got about 5-10 more yards and my rpms dropped to about 3000, but it was still too high. He then put the same shaft (which he said was the stiffest they had in store) in the Big Bertha Alpha, and I hit a few with it. Not much difference, my rpms were still in the 3000 range. Then he flipped the "gravity core" around and it helped a ton. Rpms were down now to the 2500-2600 range and I was hitting the ball about 315 yards and all with almost the exact same ball flight every time. He said he had an idea and called over the club tech to ask him. Basically what they decided was that I needed a driver with a lower CG and an x-stiff shaft tipped 1/4" to make it a little stiffer and reduce the spin rate more.
This gave me a bit of an interesting question, so I asked Bobby if I need to get my irons reshafted as well since I went up almost 2 flexes in my driver. He gladly gave me an easy way to find out: hit balls and see. He handed me a 6 iron with a stock shaft in it and had me hit a few balls and put some impact tape on the face. They went about 190-200, the usual distance for me, and felt decently solid, but looking at the impact tape they were all at least a little bit on the toe. So Bobby put a TT XP95 S300 shaft in it, and because I'm 6'3, it was an inch longer than standard, and told me "just watch this." I took a smooth swing and hit one perfectly flush with a tight little draw. 225 yards. Instantly 25-30 more yards than I've been hitting my 6 irons, and it was much easier to control too. I took a few more swings and was getting the same distances with those, and finally I decided I'd really take a swing at one. I hit a high 15-yard draw that carried 235 and rolled out to 245. I couldn't believe my eyes. Even though 230-240 yard 6 irons are never bad, there was something that sucks; I need to get a new driver and iron set or have all my irons reshafted (I was told the latter would be more expensive and that I should go on and get a new iron set as well) . Normally I would think that this is just a way to earn some extra money, but I was never pressured to buy anything from GG, and Bobby recommended that I really decide on what I want to do regarding what to buy, and never shoved anything in my face. I think I'm going to take his word and get both a new driver and iron set with all the specs he recommended. I know I will probably not be hitting 240 yard 6 irons on the course, but I had distance and accuracy gains on the monitor so I think it was a good fitting. I had all my questions answered and then some, and even though I basically had a full set fitting, I was still only charged for the $15 shaft fitting. I was very impressed with everything.
