Guys who used a lot of lead: Becker, sampras, edberg, borg, all between mass wts of 389g-410g, never had elbow issues. Their ras differed. Their string stiffnesses differed, their tensions differed, but all played high level games.
Equipment may vary, strokes too, but energy mastery does not. Quick unit turns. Quick accelerations, all use the same derived energy. It's the only thing to pros have in common: they are very fast in what they do best, such as serve well.
