Summary: I just bought the diablo irons and took them to the range and hit the 8 and my old 990 titilist. I hit half with both clubs and the diablo was about 10 yds longer and a lot straighter. Even fat and thin hits were twice as good with the diablo.
Summary: I've played these clubs for two weeks now and they are the best Irons I've ever hit. I'm a 15-18 handicap player and have used X-12, X-16 and FT Callaway Irons before. My usual fat hits are now solid flush hits and I'm gaining more confidence every time I play with them.
