What I won't do the same. I used engine brake for most of the time in long down/up slopes. It will help to increase the power of engine in up slope or help the braking effects in down slope especially in heavy traffic. You don't have to put on the brake from time to time.
For example, when I drove from L.A. to Las Vegas, I will use engine brake from time to time when I was on I.15 or I.5 from L.A. to SFO.
It is my experinece to share with you guys.
