4 iron. Hit about 190 when using a ball appropriate for my swing speed. Yesterday after a lost ball I pulled a Nike out of my bag. Hit a solid feeling drive that only went 210, so had 195 into the green. Hit a solid feeling 4 iron that only achieved about half the height of usual and only went 170! Looked at the ball and it was an old Platinum One, of which I bought a dozen back in the day and quickly realized I didn't have the horsepower to move that ball (apparently they really were designed for Tiger).
With the usual low compression balls I play, I can still hit a 3 iron well, but I get the same distance and additional height with a hybrid and can hit it out of lower rough.
