I am going through a bag of Canada Malting Company Superior Pils right now and really like it. It is very mild. It really lets the other malts and hops come through. It makes a nice crisp beer too. My only half complaint, is that it is very light colored. The beers have all been very pale, to the point a non-brewer friend told me the Czech Pils he had in Czech were darker. But, light color is not really a problem.
PS. I think CMC Superior Pils may be the exact same malt as Great Western Superior Pils. The bags look nearly identical, both come from Canada from Country Malt, both use the same description in the ad text.
