They made a plastic right after Pro that had both the small Pro logo and big Champion on it. The plastic felt like a mix of Champion with the plastic that was the old pro plastic. I have asked others about that disc and it would be very valuable one my dad has but it is not due to a big crack it got when it broke, plastic type was out for only a short time I was told by others before modern Champion came out. To me I only saw the plastic a year before Champion came out to replace that plastic.
I believe the plastic you are thinking of either said Candy Pro or Kc Pro. I am pretty sure there has never been a Champion Pro or Pro Champion plastic. I am talking only of the names, not the mix of plastic.
Although to that, I am pretty sure the very last plastic labeled CE, the Candy Pro labeled, and the first labeled Champion are all the exact same mix of plastic (whatever mix that may have been).
