Why plastic for rear skid bushings???????

Why in the world do they use plastic bushings in the rear skids?
Going to machine some out of brass!
unless there is a good reason for plastic!
any?

plastic or brass

1. Cost, Brass is much more expensive for mass production. 2. the plastic weighs a little bit less than brass. 3. Now days every ounce counts toward a lightweight sled.
