I don't think you'd want to give heading weight over distance. The problem 
with that is as if you're not approaching a point head on but to one side of 
it the angle gets steeper as you approach. If the program was taking heading 
in to account then it would start missing points as you got closer in favor 
of points closer to your direction of travel.
