Before getting fitted for the new T150 irons, I was playing the 2019 T100 irons, I love how they feel, but the performance has fallen off after years of use. The T100 irons I had were just a little too spinny for me. 7 iron spin was 7100 RPMs and had a height of around 115 feet. With the new irons, my spin was right at 6500, and my height was 104. The descent angle changed from 55 degrees to 46 degrees. Amazing what technology has done. Has anyone else seen similar changes in their numbers when switching?
