I have MX 20 for 3 years and am now considering to get a new iron set, either mx23 or j33. I'm not quite sure if j33 is that easy to hit like mx20. As far as I know mx23 is pretty much same as mx20 but J33 seems not that easy club to get a ball in the air. I'm a pretty short ball hitter, say 140 w/ my 7 iron, but pretty accurate. I don't know if I want to install griphite shafts on a new set. Or I'd like to have NS Pro 850 which is the lightest steel shaft in the market. Any suggestions for me? I'm a 10 handicaper and have been playing 6years.
