The quality is excellent and when I contacted customer service to ask a question thay were very helpful.
They are one of if not the best looking clubs on the market.The feel of a forged club with just enough cavity to to help with off-center hits.Distance is good as is accuracy.They are not so soft that they get all dinged up like some of the Mizunos do with time.
Nothing really,except that since they are not as soft as some other forged clubs you do not get as much feedback.
I have been playing for only six years and changed irons every few months until I got these. I have used them now for over a year and tryed different irons all along but cannot find any better. I play about 80 rounds ayear and am a 8 handicap.
