I really improved my ball striking today by using my pivot in such a way so as to not let my right arm straighten until past the ball. That may not be what is actually happening, but that is how I am perceiving it. In so doing, the following results are noted:
More distance.
Better accuracy.
A sense of free-wheeling with effortless power.
I don't have to think about anything else.
Not sure why this one thing delivers so many benefits, but it does. Maybe this will help someone else, too.
