I'm surprised the half-set fanatics haven't picked up on this.
Looking at the Augusta scorecard (excluding par 3s), a 300 yard drive will leave them with 50 to 275 yards to the pin on 14 holes.
Currently, pros can choose from 12 clubs to cover the required distance.
Restrict them to a half-set, and they are left with 5 clubs to cover 50 to 275 yards.
That will bring the strategy back into the game, with WITB, shot planning and execution.
