Yeah, deflection is the best method here.
The longer the backswing, you're just robbing yourself of time of the ball and will result in shank/mishits/being aced/being pissed off at your inability to return
Try and pick your spots too. It's kinda hard, but in matches you can begin to form patterns in your mind to where they're going to serve. It just gives you a bit more confidence mentally i find.
