To the extent that they both result in the proper both arms straight position yes, however 6b1d is a constant move 'away from center', which simplifies rhythm greatly - it simplifies the entire swing.


right arm thrust alone would be a move that would need 'timing', extensor action does not - that is the beauty of it, among other benefits.

thanks for the reply edz. this is my confusion. i thought that extensor action was obtained by a contraction of the right biceps, which applies pressure to the right elbow joint and tries to straighten the right elbow. this "straightening would apply pressure to the heel of the right hand, which applies pressure onto the base of the left thumb. and in turn, voila'............you have extensor action and the wobble taken out of the left shoulder.

but how does "firing the right side" differ from extensor action. isn't it the same action, and then chain reaction of the tricep contraction /elbow straightening/ right heel pad / left thumb pressure? or am i confused as to how extensor action is achieved from takeaway through to follow through?
