I hit a set of TW727M irons over at my local fitter and found them pretty decent. Wasn't cheap, a used (but clean) 4-LW (10 clubs) set in modus 120 going for around USD980. That said, I'm not entirely sure that these are still made in Sakata, Japan as Honma has been somewhat sketchy on details - some of the Tour World clubs are made in China apparently.
Good as they are, I'm not sure I'd pay that much for an MIC over an MIJ set
China is just a country
A forged press with QC specifics will still churn out same club whether its USA, Mexico, Japan, Peru it wont matter as long as machine, process and specific tolerance is the same
I've hit the 737 and no different than my 727......
