Tiger Woods explains how his iron setup and specs have remained remarkably consistent since he was a teenager, even as golf equipment and ball technology evolved over the years. "I had been playing this setup basically since I was probably about 14 or 15 years old." "Jack never changed his setup, and the 8 iron was going 150 yards, you know, that was like the standard and I hit my 8 iron maybe 160 yards." "One of the ways to do that was to have the same lofts, the same swing weight, same shafts, same grips." "The only thing that's really changed over the years is my lie angles, depends on what swing I was basically going through."
