I'll say 5 iron. I hit that pretty consistently. My last set had a 4 iron, which I hit ok but frankly it didn't go much further than my 5 iron, so it didn't make much sense for me. When I got my current set, I went with a 4 hybrid. Easier to launch in the air and definitely goes further than my old 4 iron.
