are a personal choice. I have used Titleist, Ping, and now play with Callaway. I sold the old Ping Eye 2 Black Dots, and bought the Callaway. Honestly, I liked the Pings just as well, and they were made in the 1980's! Ping created a good, solid iron that is tough to beat.
You should go to a shop and hit some irons, making your decision on what fits all of your criteria best. Don't buy based on someone else's recommendation.
