My standard loop has a preferred direction. The SW first part is less protected, and I usually have tailwinds. I come back via a more protected route.
But more importantly, I ride up the big hill where it's really steep, and down the longer more gradual slope. IOW, suffer for a short time, reap benefits for a longer time. Going down a steep hill with brakes on is just a waste of potential energy.
Also, going the other way, I'd spend too much time on the gradual, narrow shoulder part.
