Pendulum vs Tomahawk serve

Hi Coach,

These days i am practicing the tomahawk serve which i picked up from one of your videos posted here on reverse tomahawk. I have got a head start as i am able to put the sidespin on the ball as i used to do the sidespin forehand service but not in the correct manner as you have shown.

I was going through one of your promo videos and noticed that Jeff is doing the pendulum service and the sidespin he generated was more than sidespin in your video. Does the pendulum service generate more sidespin than the tomahawk or was it one of Jeff's best serves? 

Hi Shaji,

Maybe it was one of his best.  I think it is easier to generate more spin with the pendulum serve because you can swing through with your wrist more easily and so generate more spin.
