I think Cuba would be a neat place to have an international meeting/contest one day, perhaps in the town of Trompo. I bet there is a good trompo culture there.
There is that fun video from Cautin claiming a "world spintop contest" in Varadero, Cuba (discussed
here):
I asked Cautin about it when we met and he said there was no contest in Cuba. After a campaign in Spain (the first one?) Cometa took the demonstrators to Cuba as a reward. He just made a fun clip out of it.
