Hey dave I bought a "ce" cobra on ebay for 30 bucks it was sleak black and had a rainbow first run stamp on it. There is one for sale right now on ebay and the seller is claiming that there were only 300 made some black and some gold. Is this truley ce plastic or is this a first run champion cobra? The reason I ask is because I have some opaque cobras that don't feel too much different. PS thank you for the cobra it is my all time favorite golf disc. Also if you don't mind could you explain the diffrent molds and plastics that have been used for the cobra over the years.
