I don’t know if anyone else is interested in this or not, but I just got back from the world yoyo championships which also includes the spin top. There were 300 to 400 people there and they have a nice stage and sound man to play the music and announce the performers. The stage is about 30 feet long and 15 feet wide so there is some decent room to do some things but not as much space as the gym floor at NAUCC.
For a change of pace this year, I did my routine on a 20 inch unicycle. It went better than I thought it would. I was hoping to find a video of it to post here but I have not seen one yet. Maybe later?
