I stepped away from the game for around 8 years. I have been back now for about 6 months. I got fitted for a blended set of T series irons PW-7 T100, 6 T150 and T250 3-5. What I have discovered is the T100's are a bit longer than my traditional yardages. (I have played 30 plus years) and the T250's are stupid long at times for example I hit the 4 iron 230 yards on a layup hole, normal swing didn't try to "go after it". That may sound great but my normal 4 iron is in the 210-215 range. Distance control is a big concern. A couple of data points as related to swing speed I typically have a smash factor close to or at 1.5 with the driver with ball speed usually in the mid to high 150's to low 160's. Now for the fun part. My son games 620 MB's with X100 shafts. I had a extensive range session hitting his irons and wow. The feel was amazing, the ball flight was a nice mid flight trajectory and the confidence they inspired in me felt like the good old days. (I previously played miz blades) So I ordered a used set and I'm giving this experiment a proper go to see if at 54 will this work for me. I know from playing blades the drawbacks but also know the consistency in feel and distance control. So the plan is to game these and if I love them, trade the T series for a set of 620 CB's as a back up set or even go with a blended set of MB/CB's. I also may consider going full T100's if this experiment fails. Before I quit my handicap was a 2.
