I understand about the course management, but I am a firm believer that a person should when given the oppurtunity practice or attempt realistic shots, I think that helps a person improve. Since it is not a lack of distance or totally impossible shot, I would recomend to continue practicing or using your 5 or 6 iron off the tee until you have confidence in that shot. Now if money is on the line thats a different story.

But the bottom line is that golf is supposed to be fun so do what will give you the most enjoyment.
