Casey 1988
Shun the frumious Bandersnatch!
The Archon is not discontinued.
Seems like it would be too popular to be discontinued but then Innova did that with the Classic ROC. It was popular but for some reason got discontiued, almost all of the Masters and Grand Masters players that knew the Classic ROC if they played in the 1990's had one if they were not a brand loyal to another brand be it with a sponsor or just brand loyalty. Few did not have the disc and that was due to non Innova brand they threw.
T-Rex is another I can think of but then the disc was hard to make in to weight in any plastic.
