Some coach's advocate lining up your feet to the target, then preloading a twist into your torso that makes you face the side fence behind your baseline. Kinda like old Tony Roche's stance, the opposite of McEnroe's. But we might not want to copy McEnroe, with his strange styles.
Feet lined up forces you to drive straight towards the opponent. Body pre loaded allow you to unload into the serve, like a spring.
I used to serve like that, hitting some pretty big serves in A tournaments 30 years ago. But I can't find that motion as I've aged. So maybe forget that dumb idea, sorry.
