Great set of irons. They were recommended to me by a club fitter and after my demo I had to get a set. I have the graphite shafts. I had been using steel but tendonitis in my R arm/shoulder necessitated the change.
I have removed the 3 and 4 iron as I find I can hit my hybrid and fairway woods better although they are not as hard to hit as other sets I have owned. What really shines though are the 7-PW. The forged steel heads offer me a soft feeling with a nice high trajectory. As an added bonus, Ive even added a little distance, say 5-10 yds each club.
Mizuno MX-900 are now very affordable as they have newer models out now.
Highly recommend them to any mid to high handicappers.
