I have been playing my TM Tour Prefered irons for about 4 years now. Shafts are Dynamic Gold S300.
My tempo is fast, specially in the backswing (trying hard to slow it down), but my ss during the downswing is not fast really, to give you an idea it´s about 98 mph with a 3 wood. The distance I get with a well hit 5 iron is about 165 yards. I hit it pretty straight, medium trajectory (I don´t flip my left wrist but I do not compress the ball either).
When I swing my irons, I don´t feel them heavy, but I have the feel that I don´t get the shaft work because of, probably, lack of ss. I could swing harder but I would ruin my swing.
Having said all this, I guess that in case you don´t have the proper shafts, it is less harmful to play with “stiffer than you need” shafts rather than “softer than you need” shafts, but, Should I consider shifting to regular flex shafts?
I don´t have many options to test some other irons, so your feedback would be very helpful.
Thanks a lot.
