Sometimes (I should really say always) the answer is just to hold the club so lightly, that if you held it any more lightly, it would fall from your hands ... and keep it that way throughout the swing ... There has to be trust that we are not so much holding the club as we are allowing the club to become glued to our hands through the nature of the waning motion ... ahhh! magic!
The struggle of method entices the hands to inject themselves. The thumb on the cymbal represents the hands in the swing. Can we dance the hands so lightly on the cymbal that the Centre does not become deadened. This kind of thought is the culmination of a long struggle for me personally in my own game. Attempting to let the hands go and really letting the hands go are two different things. One is a contemplation that innervates the hands, the other is a sense of trust that develops as you attempt to hold the club more lightly, and more lightly, and more lightly. Suddenly the pure view of the ball ... commence movement. swish!
Now putting ... that's been a true thorn lately. But I think the same line of reasoning applies.
