"RIPPING" the ball is not a rallyball.
It means that one in 10 pure winner attempt, using all the kinetics AND musclepower you can gather for the stroke.
The player is tense, grimace on his face, he tighten the grip, usually he really jumps hard into the shot, and he's using muscle as well as good form to hit this ball. He cannot RIP every shot, or he'll tire out before the 4th game.
A rallyball IS a fast easy, smooth and relaxed swing. Easy means you can do it all day.
