I voted 'Only trim when needed' for growing long hair - i.e. when your hair needs it.
My ends are a little thin but the actual hairs there seem quite healthy. I'm currently just trying to get on top of splits that appear throughout my hair but not going crazy or worrying too much. For me the damage doesn't appear to travel up the hair shaft, but for others it does. So you can see, from the range of answers already here, it really does depend on what your hair needs and what your goals are
