Any common sense logic on how the pins/clips face.

I always try to put them in so they are the most difficult to remove. Sometimes you'll hear stories about pranksters removing the pins just for fun.

This is why myself and others, drill out the little hole in the pin a bit and put a tiny, key operated padlock in place of the clip. Still only going to keep the smalltime pranksters at bay but every little bit helps. A sturdy lock on the release handle is a must. Hitches should come from the factory with a release handle lock.
