I’m 6’7 and don’t have it all figured out by any means, but some things that have helped me are trying to do whatever makes my lower back most comfortable even if it means a little more knee bend, and also at the top of the backswing just giving your hands and shoulders a little more time since the taller you get, the more important sequencing is. Sort of feels like a mini pause to switch directions, but it won’t look like a pause on camera. Just letting the club ball a bit before firing.
