There is no one best method. In most hitting sports
(tennis, ping pong, baseball) the hitter has several
different methods to master to be an expert. There are
serves, top-spins, lobs, bunts, hit-and-runs, etc.
I love the tinkering "method" and will probably
stick with it.
But maybe I'll tinker with it.
I always admired the hall-of-fame pitcher Juan Marichal
who came overhand, underhand, sidearm, high kick, low kick,
slow, fast, curve, slider, fastball, change, etc. and
almost always got his man.
