The most universal thing I have found is secondary tilt at impact…so much for covering the ball, but that’s a down the line issue that people misinterpret. A whole different debate.
One would surmise starting with some and maintaining it would me the most efficient, but Tim Clark would be one that does nothing of the sort…ad there are others. So that’s out the window
Different grips, stances, alignments, paths, face to paths, AoA, backswings, transitions, etc. Nothing universal when you watch guys like Jim Furyk and Nicholas Thompson succeed.
All that’s important is the part match.
I have gotten in some pissing matches over the last few years with people who want to force lag into a swing that can’t handle it. Swinging more left on a swing that steepens in transition and early extends the path out to the right.
Technobabble aside, the parts have to match and if it’s a flipped fade or a draw with shaft lean, the parts have to match.
That is your job if you aren’t working with a competent pro. If you want to make a swing change, educate yourself on how to match things up.
For example, if you look at your swing face on and there is a gap between your right arm and your body coming into impact, your arms need to start sooner despite the old “Works from the ground up” theory. Which is one cliche I agree with, but from a feel standpoint, you may have to start your arms to match your active lower body…or vice versa.
If you start any statement about what your working on with…”They say,” or “I heard,” start over again.
