Put the line in the release and see how hard you have to pull to trip it. Adjust to a reasonable release tension. If you over-tighten, it may be impossible for a smaller fish to trip it, or more importantly, for you to trip it when you bring in the rod. If too loose, it may trip when you turn the boat or pick your speed up. For Lake Ontario, I keep them relatively tight to get a better hook set on the initial strike.
