Cwing I don’t want to have a set back
Trust me, you won't have a set back. I've never noticed any changes in my swing going from steel-graphite-steel-graphite. I may not take the same set of irons out 2 times in a row. And hardly ever, drivers, which I always take 2 of. Scores have been within 2-4 strokes every time, and may not be at the same courses.
I once did not play for almost 21 yrs.; never picked up a club for anything. Last 9 hole round was a 41. I bought a set of old irons/woods from a thrift shop 1 day, coming out of the barber shop next door. $1 each. And bag. Drove straight to a course and shot 42 for the 9.
Like Bagger Vance said.........😉👍.
