Yes, I do believe the most efficient way to play golf is having the same feel for every club and shot.
The difference in swings are going to be dictated by ball position, length of club, posture and length of back swing (the only thing you should have any conscious difference).
The important part is to have the body parts in sync the same way for every club and shot. The hip and shoulder rotation, the natural, constant release, etc.
The more things that are constant, the more you will be able to repeat them.
An LW is a short club and the lie angle is more upright. This will promote a more upright, steeper swing and by virtue of the ball being father back, a very descending blow at the ball.
The driver is longer, flatter lie and the ball position being farther forward will dictate a flatter swing and a less steep angle of attack allowing you to hit it on a level plane…or as some like to, slightly on the upswing.
A knock down shot will have a different angle of attack by virtue of ball position and the spine being more in front of the ball at address.
You get the idea. The point is to have one general, in sync feel that works for every club and most shots.
The exceptions are funky shots like massive hooks and slices from out of the trees and such. Possibly a slight change in perception when you work the ball the opposite way for what is your natural shot.
My father-in-law was about a 35 handicap and he once told me he had about 15-20 different swings he would use.
I then told him in the course of a good round of golf, I would have two. My regular swing and one that creates a different kind of shot.
He then told me about all of the hand manipulations he would use to hit different shots with different clubs. I told him he didn’t hit different shots…they are all the same bad shot. 😀
As soon as I convinced him to stick to one way of swinging, whether it was a 20 yard pitch, a 5 iron or a driver…he immediately improved to a 25.
Every different swing he had was a direct (and usually incorrect) implementation of a Golf Digest article he had read over the past 20 years.
The breaking the hands and fanning the club wide open at impact to hit a high soft chip (flop shot), was my favorite. He alternated between blading it over the green and fanning the club so open, he would go under the ball and advance it a few feet…or less.
