As an RF Engineer and an antenna designer, I can say that you don't want 180's. Go with the 120's or even some 90's. You'll get pretty good coverage all the way around even with a couple of 90's back to back. If you are really worried about the small nulls on the sides, make sure your main beam is pointed to the highest traffic areas.
