Hey thanks all for the kind words. As you might be able to tell, I have the first trick fairly solid, but the other two not so much. As you can see by the last one it is possible to do without bearings, but I'm not sure how solid it would be possible to get, I found that even when I landed it, the suicided diabolo ended up with no spin (and I think it loses it all quite early).
The basic trick with bearings is actually probably easier than it looks, especially if you can do a fountain with poi.
Sorry about the music, I chose a band I knew personally as i figured it would mean the copyright wouldn't be an issue.
