I typically drive them to the corners and get a nice weak lift to the back (where my partner can get it) but then I think there are better options. The other one I do is a net drop which forces the opponents to lift it up, but then I feel this one is so typical.. and not useful when your opponent lifts them so high and far back. And then there's my partner's nice push to the side (just at the service line) that catches opponents off guard. The reason I refer to as my partner for this service return is because I myself can't do it yet, but he does it so nicely. Any others, variations? Or ways to improve?
