In that case, you can say MMPR for a default, because it's physically impossible to go wrong with a classic in this case, and most of the PR fandom agrees because of Tommy Oliver.
Also, side note, Jason David Frank (Tommy Oliver's actor) shot himself last year. I'm still a bit upset about that. For reference, Tommy Oliver was the first Green Ranger and the first Ranger to make a re-appearance in a subsequent team (after he was replaced by D.J. in Turbo his next appearance was Dino Thunder). It was once said in Ninja Steel that "Anybody who's ever been a Ranger knows Tommy Oliver" (paraphrased).
