remove heat?? yes or no opinions

The heater in my Duster sucked too until I flushed the heater core, fixed all of the vacuum lines, installed a new HVAC control box, and put in a new thermostat. Now it works great.

I don't think removing the heater is worth the small weight loss. I'd only ever remove the heater if I was building a race car; I can't imagine driving in cold weather and not having a heater. I did remove the A/C from my car but that's because it didn't work at all and it doesn't get hot or humid here enough to need it.
