Please don't get me wrong. These paddles are not doing the same thing as the bell hiller head other than making the cyclic response faster. These paddles increase cyclic response by making the heli less stable. The Bell hiller head increases cyclic response mechanically (reduces the percent of blade rotation needed to apply swash movement to the flybar). Lightening the flybar simply decreases the centrifical force (gyroscopic effect) and reduces over resistance of the blade "disk" to a change in attitude....thus cyclic response is quickened.
