Comments about Hireko USTIRI:UST iRod Iron Graphite:
I'm no pro, but I like a club with a solid feel at impact. I don't swing hard enough to hit a stiff shaft but really hate "whippy" feeling shafts. The specs on the iRod R-flex were promising. After matching these iRod shafts with my new Acer XK Ti-Ceptional irons I think they are as good as the specs show. They have good feel and appear to be consistent from shot to shot.
