I agree that 18 short risk/reward short 4s would be monotonous.
So may of the great fours can easily be played with a 5i and a wedge. For me the truly tempting ones are 260-290, and the tees I usually play due to low handicap means that most short par fours are at 300-330.
The Mass. Golf Association started conjuring a few short 4s during the match play portion each year in the Mass. Amateur. Last time I came up against one, it was 295 with perhaps a 285 carry to the green. This was out of my range, and even though I was losing at the time, I still hit 5i off the tee.
