I started golf around 2004, having played football and baseball in college. I loved hitting drivers, and over the years I've competed in the remax world long drive comps. I am constantly tinkering with different driver setups from 3.5 degrees of loft on xxx stiff hof shafts to 42 inch Fti squared heads. The other day I got paired up with a guy who was hitting a titelist 975d in an x flex Fuji at 7.5 degrees. I got into golf only about 10 years ago so these drivers were never on my radar. After seeing the amount of roll he was getting I asked to hit it on a couple of tees. I was amazed at how solid and how far the ball went with such old techology. I found another 7.5 975d at my local golf shop for 15 bucks in an x flex. So I decided to do a test against new tech. I compared it to the driver I currently game, an 8.5 callaway x hot with a 2x hof shaft standard length. Here's what I found....at 131 avg swing speed with the callaway after 6 balls the average drive was right around 340. The 975d had an average of 129 swing speed but produced a higher ball speed than the callaway with the average drive falling around 345. Comparing dead center hits between the two clubs, the 975d was every bit as if not longer than the x hot. In my opinion the only thing new technology has helped the modern golf game, is on off center hits the dispersion is much better. The workability of the smaller head, the more lower and boring the trajectory of this club makes it an unreal gamer in your bag. I wish I would have found this club sooner.
