Hi,
I play off 5 to 7 hcp and have lately used Mizuno MX-300, X-20 Tour, X-22 Tour and currently Diablo Forged (USA) iron set.
I really love the Diablo Forged irons, not quite as forgiving as X-20 Tour but a far superior iron for feel and accuracy.
Unfortunately I didn’t like the Mizuno MX-300 4 to 6 irons, just seemed foreign when compared to 7-pw, the longer irons just looked a more compact head.
P.S.: I originally purchased the Australian version of Big Bertha DIABLO irons, very similar to Diablo Forged, different back plate and grooves, didn’t like, think they were designed and produced prior to Diablo Forged in USA. I purchased the USA version and much happier.
Kind Regards, Ken
