Darin, Use a ladder to access roofs that aren't under a TIP!
As you know Boise and Canon City share nearly identical climates......topping sucks but willows take it in stride here. I ve worked on a couple of willows tahgt split out 1/3 of the canopy in one swell foop- I didn't reduce the remainder at the time but they took the natural carnage in stride. The Willows that other people top just blow epicormics all over unless they already have cytospora or some other fungal disease.
