Hi Indiantwist,
Thanks for the question. Hopefully I can give you a little guidance.
You said, "However my serve is way off whenever i do it with WW.
Iam not sure what is going wrong here. I use continental grip and i hit a flat first serve and a kick like second serve. I seem to be hitting the net all the time."
What may be happening, at least on the kick second serve is that the Wonder Wedge has caused you to close your racquet face slightly as compared with the standard shaped handle if you are using the Continental grip. In addition to this, the increased leverage and traction will cause you to impart more spin to the ball. At first, you will draw the ball into the net. I always make this predication to first time users of the Wonder Wedge that tell me they use the Continental grip and hit a spin or kick serve. They always seem to be amazed and say, "How did you know that?"
What you don't realize is that the gift is right there in front of you, in the net. You have to make the slightly more closed racquet face and increased leverage and traction work for you. You have to practice and experiment with your mechanics to generate, as I like to call it more forward/horizontal
energy. A great drill to help you realize what is going on is to take a basket of balls or whatever you have, practice you kick serve but try to power it all the way to the other base line. Pay attention to the spin and action you are getting on the ball. You will have to be aware of what adjustments in your mechanics you made to accomplish this. Don't be judgemental, just let it flow. In this learning, understanding situation, the only bad thing you can do is hit in the net.
Check list:
How smooth is my service motion?
Is it restricted or do I have a full range of motion loading all the muscle groups? (You must be relaxed to fully load the muscle groups.)
How good is my shoulder rotation?
Am I making full use of my triceps and wrist and powering through the ball?
How good is my follow-through?
When you understand and adjust your mechanics to master the new points of leverage and traction you will be amazed at the improvement in your serve.
You got to love the game.
