climbing beans at 45 degree angle

I want to grow climbing runner beans up a single row of stakes set at 45 degrees.

I want to do this As it will shade other beds alot less. also I want the beans to hang down below the foliage for easier picking.

I am unsure as to the orientation. My long beds run north-south so they get equal sun on both sides. Will the beans climb the poles or will they all try to face south?
