I love the mizuno mx 23. Used to hit the mp 30 and those are sweet also. Cant go wrong with MIzuno irons. Mx 200 has a hugd sweet spot, those are next for me.
You MUST switch to CG14. I bought these a couple weeks ago and scored a birdie from 110 yrds with my 52. These are amazing from the sand. Will get it out of the bunker for sure. Amazing clubs.
