Like I said in the General post, the white plastic is not "cheezy". It is a different plastic. I am running with the white plastic with no problems so far. The Cougars are also built with this same updated plastic and have had no problems so far.

The metal impellor adds reciprocating weight to the camshaft. Plastic helps it rev faster because it's lighter. Very subtle though.
