Comments about Hireko I3390:Oxygen Type-X Iron - Clubhead:
I purchased this set about six months ago. I had been playing the Acer XP905s. I am sorry to say this but there is no comparision. The Oxygen is the winner hands down. I built both of these sets with the same type graphite shafts so I could compare. I do wish there was a lob wedge for this set.
Comments about Hireko I3390:Oxygen Type-X Iron - Clubhead:
These irons look great at address and are easy to line up. The undercut channel moves the weight outward making it very forgiving. The shot peen finish is very easy on the eyes. Highly recommended for high and low handicappers.
