Clubhead speed is paramount in achieving the proper launch conditions to have success with long irons.
If club head speed isn' ideal. Hybrids just launch the ball with such ease.I only have a 2H. Its basicly a 5w with a shorter shaft. It's used as max distance club, not for distance control.
I preffer long irons into greens.
I used to carry a smaller set; back when I walked more. A couple clubs to get inside 150, a couple clubs to get home from there, and a putter. I enjoyed doing it and it didn't effect my scores one way or the other. One benefit, aside from the simplicity, is that it requires a bit more creativity.
