I am looking for help selecting an iron shaft. I am 60 years old and have lost distance over the past 10 years. My 4 iron is now only about 180-185 and my 7 iron is about 150 -155. My current set of irons is the original 2020 T100 irons, I tried the Tensi blue graphite shafts in regular. (My thinking was increased speed and softer feel). These irons never had the softer feel I was seeking, I may be getting 5 more yards over steel shafts - but these feel really light and rarely solid. Is there a steel shaft that would give me the solid feel and match the T100S heads for maximum distance? From the time I was 20 - 40, I played X100 shafts and they felt good to me, I realize they are not a good match for me now, but something has to be better than what I have. My driver when hit squarely goes about 275-285 consistently.
