We've discussed fast bowler actions to death. What about spinners?
I think Warne had the best action. Was so smooth, and involved so much shoulder strength it was hard to imitate properly (others like Steve Smith and Cameron White dabbled at imitating him but never got those shoulders involved like he did). Also the walk to the crease was pretty amazing. A casual stroll but with steely determination.
Abdul Qadir, Harbhajan and Narine would be the next tier for me.
Also, Carl Hooper for being so lazy with it.
