I rarely double-fault either, but still, I'd like to have more of a pro-looking second serve. What would you say is the key to consistency with your kicker?
As much racket head speed as I can humanly create haha! The other thing is Toss placement. As long as I get a proper toss slightly left of 12, and tons of RHS I'm golden it seems! Confidence is key really. If you have faith in your kicker it will work out, as soon as I get hesitant it doesn't work at all and I start to send it long.
