I'm looking at purchasing a set of Ping G20 irons. I currently have a set of Bazooka irons with graphite regular shafts. My swing speed was tested and showed slow (65-70). I'm sure it won't get any faster at my age (66 yr young). I was thinking at getting graphite senior shaft but liked the crisp feeling of the steel shaft. I was told to get the Ping steel "soft regular" instead of the graphite. I really wasn't aware that senior shafts came in steel. Does anyone have any comments on the Ping G20 irons and recommendations on the differences of the shafts available? Thanks for your comments and help.
