My 2HBH is reliable and I hit it with decent pace and spin. If someone hits hard, I can return or redirect with pace. However, when I get a slow, short ball I have a hard time hitting a screeching DTL winner, Djokovic style. My shot has too much topspin and doesn't really penetrate thru the court. I have no problem hitting fast paced winners off my FH. Do I need to turn my top hand to more continental/eastern grip to flatten out DTL 2HBH?
