It's best to have as many options as possible here depending on whether you are facing hazards, the fairway condition, if you are in rough etc.
I carry 4 wedges so that I can vary the length and height of my shots, I can choke down on the grip, I can vary my backswing length but I will always swing at the same tempo.
I will also punch shots or make long chips with
irons up to a 5. Become comfortable with as many options as possible in the short game.
