Droplet did one last year, and does a duo this year with another mini child. Both times I have paid through privates to have it choreographed by a coach at the gym and I have gotten the music myself. I used a mom I found out about on this board that does a wonderful job with it and she did both last years music and this years.
It's been fun.. Droplet has decent tumbling skills for a mini and it gives her a chance to use them on the mat, since she is otherwise on a level 1 & level 2 team. She will not do one after this year, so we are enjoying it while it lasts. It's usually the smaller competitions that we do that offer it.. (Xtreme spirit, Americheer, sometimes CSG/nations choice) and we always go with the team. Never alone. I would never go without a coach. We are doing one competition at the very end of the season with our half season teams, but our regular coach goes to those so it's no different.
