In early June I went and did a fitting for the TaylorMade P790s. First set of clubs I ever got fit for, fun experience.
Since I knew what club I wanted, it was all about finding the right shaft. My spin rate was too low for a 7 iron (should run between 6500-7500 ideally) with the first, heavier shaft to we dropped the weight some. Then I started pulling my shots. Finally settled on one that gave me the right combo of higher spin rate, good launch angle, and more of a spread centered on the fairway instead of dead pulls. It was cool to see how much my ball flight changed just by switching out shafts.
I also averaged 185 carry with the 7 iron, after not playing any golf in nearly a year. These clubs jump.
