DOT-5 is the only brake fluid you need to careful about, that will deteriorate the seals in the brake system over time.
Whenever I pick up a new car, I typically flush the old shit out with synthetic DOT-3 (Castrol), then switch over to Super-blue (DOT-4) if it's going to see track time. I've never used the Ford Heavy Duty, though I've heard it's good stuff. If you've got money you want to burn and never want to worry about boiling, get the Motul RBF 9 billion, RJ seemed to like it in the Typuh-arRrRRRR.
