I'd say filling the hub is better for the well-being of the hub. It keeps both water and dirt out, and may continually replace the grease that the balls push out of the races (just a theory, not proven). In your case, the slower unloaded spinning is not a problem at all. I'd do what you're doing if I rode in bad conditions, but i seldom do.
