Hi. What si the effect of bending or cocking your wrist while serving? I noticed that when I do this my serve is way... way better. More spin, more power and more consistent. I grab the racquet with a continental grip anyway but my wrist is more bent. A bit like Raonic. http://www.youtube.com/watch?v=klR6AfFR70c What is the effect? More spin? More snap through the contact point? I never heard anyone talk about this.
