This is my 1st post on the forum (take it easy on me!) Very interesting topic. I used to own a small club repair/building shop 30 years ago and still do quite a bit of repair out of my garage. I consider myself "old school" but find the MOI stuff very interesting. I've always been a big believer in SW. Play my irons at D-3, Driver at D-5 to 6 and wedges heavy D-8 to D-9. I've always felt the need to FEEL where the clubhead is during the swing and that the extra mass delivers a more powerful strike w/o any significant loss in clubhead speed. I do know that even at 62 yo super light shafts are not good for me! Great topic!
