We used to have a golf tournament in the Oakland, CA area that was for a radio station 97.3 FM. You could take a 9 iron, a 7 iron and a 3 iron or 3 wood with a putter representing the 97.3 station. Punching 9 irons in from under 100 yards was certainly an education.
I used to do something similar on occassion walking 9 holes and just taking 3 clubs. Never just one. I have shot some really solid 9 hole rounds with a 3w, 7i, w.
