The thing is, at the end of the day you just want to hit the ball well. For me it's about swinging up for topspin and then I set the racquet angle to adjust height over the net. In the couple of hundred milliseconds that I have to decide what to do, that's about all I can handle.
Then I just try to maintain the angle through the contact zone and put the ball on the sweet spot. If I manage to do that the ball goes pretty good.
