I obsessed over stuff like this for a long time.
Then I watched Soufi run out from all over the table and realized the mechanics do not need to be anywhere near perfect to play professional pool.
I then watched an online discussion between pool coaches and one of them mentioned that all your focus should be in front of you after you get down on the shot.
That seems to be the trick. Get your alignment, grip, and stance decent and have fun.

Holy old post! Grudges are strong, eh?

Doesn't look like a 70-year-old stroke to me! But I know a couple of 70+ players with really good games. Maybe we need to redefine how we think about that. Matlock seems to drag himself around the table pretty well still.
