Per title. I ask because lately I have to aim and adjust to hit closer to the net in order to have more power or the ball will be long. I aim and adjust by hitting more thru the ball and consciously closing the racket a bit, but I thought this was a mentally tedious and ineffective way of hitting every shot because I cannot zero-in on the degree to close the racket and hitting thru the ball doesn't give a lot of topspin. I was amazed at how freely and powerfully tournament guys at the court hit the shot and the ball lands in a general area safe and sound which they didn't appear to do any aiming. Am I support to aim at net clearance or where or not at all?
