Any other (bicycle) route planning tools like MMR's Route Genius out there?

I love the idea of MapMyRide's Route Genius, but the difficulty I have with it is that there's no way to mark sections of road or trail as areas to avoid. Hereabouts, Google Maps appears to have purchased the right to use plat books without actually having bothered to verify that some (a lot) of the roads are navigable or even still exist; in many cases the plat books are decades out of date, and many "roads" have become private property or degraded to the point of non-existence.
Another issue I have with Route Genius is that it doesn't try very hard to find a variety of routes.
Anyone know of other similar tools?
