In general I have no problem with composites. What drew me to the aluminum impeller is 1) aluminum also no galvanic problem against aluminum but also the shape of the fins is supposed to be more efficient pushing more coolant. I will definitely post if that turns out to be a bad idea.
Just realizing that I still have my "placeholder" dorman reservoir and hoping that doesn't have to come out to change the OFHG because I didn't order a new one. (from experience those are usual one shot they like to self destruct on removal)
