Hey Will ,
Great post , clearly identifies the choice of leadership style lying on both extremes on the continuum , However I believe in reality a creative mixture of both styles , somewhere in the middle is what defines a great leader .
Flexibility is what is called for in our dynamic environment , and the most effective leadership style must be contingent on the elements at hand .
I agree with john that finding that  "Sweet Spot" in leadership is what fires up a campaign .
