Summary: Have been playing Nicklaus VCG irons for the past 10 to 12 years and felt it was time to get something new. The Wilson Di9 irons have proven to be just what I needed. My swing speed has decreased considerably the last few years but with the Uniflex graphite shafts I've found that most of my shots are traveling a bit farther. These clubs make it so much easier to get good loft on the ball that it's amazing.
Summary: I am an older guy with a slower swing speed. I had been hitting Fat Shaft II irons for nearly ten years and decided it was time for an upgrade.Because I felt good about my old Wilsons, and because no one else plays them, I bought a set of the new DI 9 with graphite shafts. WOW...what a difference technology makes! Ball seems to come off the face much better, I am hitting longer and they are easier to control than my old sticks, which were pretty forgiving too.
Summary: It took me over 5 hours to finally decide on what set of irons I was going to purchase. After hours on the simulator and hitting over 150 shots with 7 different 6 and 7 irons, I could not believe the the DI9 set was what I left with. I kept telling myself NO WAY, Let me try the Burner 09 again, or the Mizunos, or the Titleist AP2, or the X22, or the Ping G15 (almost got those great irons) but not one of those irons compared to the value of the DI9.
