Actually, I WAS being nice. But a 25-35% grade (or even a 15% grade) is going to cause you to speed up very quickly if you are coasting in 4th gear. If I don't drop my truck into 3rd, when I'm going down the 6-8%, 8 -15 mile grades here in Arizona, I speed up, cruise control on or not. And, I don't want to do that when I'm pulling a trailer (and I damn sure don't want to ride the brakes).
