G.S. Tennis with or without nunchuck?

Playing the game and having a hard time getting better. I am not blaming the motion control either. I know it was my stroke and I begun to practice fixing that. However I was wondering for those of you who play do you use the nunchuckor just use the controller? Looking for opinions not an arguement for which one is better please!To each is own! Details why you think so would also be nice, but not necessary.

I prefer the Nunchuck, but when I started I used it without the nunchuck to get the timing forehand and backhand down. I just like to have control of character while I am playing.
