I'd also work on my pivot if I were you. Learn to turn and swing from the feet.

The McDonald "walking" drill looks like it is made for hooking up the footwork with the upper body work.

Another good rehersal is to place a club across the shoulders, one hand at each end of the club, assume the stance and turn back and through, back and through, back and through. Into a full finish. Not swinging a club that flies off and pull your shoulders to the finish is actually an advantage in this drill. You are forced to move your hips and shoulders all the way to the finish by using muscle powered motion all the way.
