As far as TOPO maps. I have yet to find a trail that is on a TOPO that is not on my CNNT. I don't see the need for the topo personally. The CNNT maps are that good...
I like having topo maps because they show the contours of the terrain, and that lets me pick more interesting roads. If I am just following my nose, I can glance at an upcoming side road and see if it goes through a valley or across a wide flat area, or up a hill, etc. I enjoy that extra level of info, but as you say, it isn't strictly necessary.
