Decision point coming soon

I have always planned to cruise the Rochdale Canal and then on to the Leeds and Liverpool but I met someone the other day who said I MUST do the Huddersfield narrow. Now both have their challenges, particularly for the single hander. In fact, CaRT say that the vertical lift bridge on the former should not be attempted by solo boaters. The latter has a 3 mile tunnel which I wouldn't relish. Has anyone reading this got any tips or suggestions? This post is a result of what one does when having to sit in a laundrette as I have today. The first time for forty years (They haven't changed much).
