Dan,
Yes, I know what you mean that it is hard to judge the ratings on easier climbs. I really liked the climb, particularly since I only had a written description of the climb and not a photograph of where the start was. I guessed right about where the start was. I really liked Pitch 4 although it was very runout. I do not think you should change the climb, but rather it might be good to let people know that Pitch 4 is a heads-up pitch.
