I use the 2 when I am dealing with seas. I find that I can't get the bow down on the back of the waves and pound too much with the 3. I just don't seem to get the power I need on the front of the boat with that little hanky up front. We have a short gap between the waves on Lake Ontario and we need power off the backs of all the waves. I don't know what it is like where the swells are bigger and gaps between the waves are longer.
