Bicycle Mechanics - Avid SD7 Install - Cable to Noodle Fit

I have a couple of quick and dumb questions, but I figured I'd ask rather than assume. I am replacing my Tektro V brakes and levers with Avid SD7 brakes and levers. The cable ends (which go into the noodle) have metal ferrules on the ends. These ferrules fit into the noodle for the Tektro brakes, but do not fit into the noodle for the Avid brakes. The instructions for the Avid brakes didn't say anything about threading the cable through the noodle, or using a ferrule. I looked at the instructions for the Avid Flak Jacket cables online, and they stated not to use a ferrule when attaching to V brakes.
Am I correct in that I wouldn't use a ferrule on the SD7 brakes? Also, what is the best way to remove a ferrule, without shortening the cable housing?

If both ends of that section of housing have a factory-crimped ferrule, than youll likely have to cut it. The noodle performs the same function as a ferrule. If these are new housings that came with the brakes/levers, than there should be plenty of length for you to trim them with no fear of them being too short... Just be sure to pull the cable out before cutting the housing (Thank YOU CPT. Obvious!).
Thanks mactheknife68. I ended up replacing the rear brake cable and the rear section of housing. For the front, I just cut off the ferrule. The cable housing fit great into the noodle without a ferrule, and the brakes work excellent. I only did a brief test in the neighborhood yesterday though.
I was amazed with how much friction the one ferrule (on the top tube, on the rear section of housing) had picked up with only one season of riding. The cable and 3 feet of housing only cost $6 at the LBS, so I will probably make a habit of replacing the cables once a season (at least the rear cable).
