Anticipation + idle in neutral is the best option. The more you anticipate, the more you save, and the more you are safe. Don't forget that driving without brakes means you loose each time you use breaking, with the brake pedal or the engine break
Engine break is interesting only if you have been pushed to go too fast and you have to break, not only slow down.
Have fun,
Denis.
