I consider myself a good consistent HALF volleyer.
I seldom hit topspin. Usually, a combination of slice and sidespin.
My swing goes from higher to low, so an open racketface can hit the ball over the net and not too high, barely skimming the net.
I know Sampras hits a topspin half volley quite often, as does Federer.
I'm nowhere near their skill.
A local former 5.0 also hits a topspin BACKhand half volley.
But everyone underspins their volleys.
