I was just wondering if anyone had any hints, advice or tips on developing right hand(or picking hand) dexterity - most particlarly in regards to playing rhythm in a funk style;developing a really fluid, fast and responsive wrist action to get that neat flick of a sound usually across the top four strings.

Obviously there is practice, practice, practice but I just wondered if there was anything else to loosen my wrist. Yoga/Pilates for wrist flexibility maybe?
