I find that drills are very good for working on technique, but that the intense focus required to change any one element is so great that it's best done in short course ... focus intensely ... rest ... repeat. I think long course creates an opportunity for fatigue to creep in and sloppiness / old habits to emerge before you've encoded the new habit.
