Which are the "Freddy Fenders"? On the PlanetBike site I see "Hardcore Recumbent" models 7010 and 7011 (front and rear) for 20" wheels, are those the right ones?

Can anyone comment on coverage vs. the factory fenders on the NS model? I have extended the rear fender by about 6" with a black duct tape mod but still get drips & drops up on my backpack.
