The subject says it all. I am more of a power player and in singles matches I tend to get into "topspin / baseline" mode, trying to hit deep, cross-court, attack the short ball, etc. I want to start working a little more finesse into my game, specifically working in some drop shots especially against counter-punchers that position themselves defensively way behind the baseline. I can work on most of the technique aspect on my own, but I want some ideas on what specific scenarios in terms of opponent position and type of incoming ball to try the drop shot. It also seems like the pros are using this shot more often and when hit from the baseline it's almost always a cross-court dropper. Is that correct?
My only technical question is on the forehand: I use a semi-western grip. Hitting a drop shot on a higher ball is natural, but do I need to try to switch back to continental at the last minute to drop lower balls? Should that discourage me from trying it on the forehand unless the ball is high?
Edit: One other things is that I am a lefty. I'm not sure if that should make my pattern of use of this shot different than for a righty?
My last two tournament match losses are to lefties, though I practice with a lefty (my son) all the time.
I'm also an aggressive player and over 60, and so when I target an opponent's backhand, I get a lot of underspin shots back. I also find that age group opponents play several feet deeper than normal against my shots and so learning a drop shot has been a critical skill. I'm better at it in practice but don't yet have the competency with it to have it be truly effective in match play, though sometimes just the threat of doing it is enough.
I would never drop shot off a high ball - I feel any high ball I can drop shot off of, I could do more damage by hitting it. I've come to realize that developing a high level of competency in a drop shot isn't necessary - if just having a mediocre drop shot forces my opponent to play closer to the baseline than they would like against my regular groundstrokes, that's a huge win on my part already.
I've also found that because I still hit topspin backhands on a large percentage of shots from that side, that when I go to hit an underspin, my opponents will automatically take a couple of steps forward so even though I can hit a backhand drop shot with more disguise and shorter in the court, the advantage is negated by my opponents being closer and already having their weight moving forward.
Last thing for me is that I've found my opponents are much more capable in doing something with a drop shot off their backhand than their forehand. Sure, they may be able to hit the ball better off their forehand but I can more easily get to the range of shots hit from the forehand side than the backhand side, where it seems a backhand with a continental grip can re-drop, hit a sharp angle across the court, or have more control to bunt the ball into either deep corner.
So that being said, I've been working on my forehand drop shot, and off the typical pattern of driving balls into my (righty) opponent's backhand, eventually running around to hit forehands inside out, and then hitting a dropper to their forehand side.
If I could ever get the voices in my head from overwhelming my thought processes during tournament matches, I might be able to employ this more than I currently do.
