I believe the cat has been edged out because of it popularity. Mono is the dying class and remember, it is always darkest before the dawn. The Olympics leave themselves in danger of being outdated and relegated to "old style" sailing.
One does well to remember that the "freestyle" swim event did not exist in the earlier Olympics of last century because it had not been invented yet.
Surely now the latest style invented is the premier swim event.
No multis in the Olympics......this will become a documentary of corruption and back room shenanigans.
