Ha! Good idea to start promoting the World Spintop Contest in Iceland!
Although those countries are members of ITSA, we do not expect players from many of them, but there is no harm in hyping it a little.
By the way, Cuba is not yet a member. I think you got confused with the Puerto Rican flag that has the colors inverted.
ITSA has members of a total of 16 countries (I have Hong Kong listed as a country but it could be replaced by China which is not listed).
Missing from the video are Australia, Netherlands, Pakistan and Philippines (the flags of the last two also missing from the website, as they are Junior members, but I will add them soon).
I think we should make a "See you in Iceland video", like the "See you in Tokyo" made a couple of years ago by the yo-yo people. What do you think? I would need a short clip saying "See you in Iceland" (in whatever language you want to say it), preferably with a top spinning on your hand or doing a trick. Even if you are not sure if you are going, but if there exists the slightest possibility, I would like you in the video.
