Am I allowed to use tennis balls, juggling balls, detached counterweights, or hacky sacks in my freestyle? This is pertaining to Sports Freestyle Division. Thank you for your response.
I am asking this question due to the nature of the rules:
“All contestants must conduct their freestyle with the safety of the audience, the venue, the equipment, and themselves in mind. Contestants performing in an unsafe manner may be disqualified at the discretion of the judges.”
“The contestant is only allowed to bring yo-yos, strings, counter-weights, gloves (or equivalent items), a backup music CD for competition, and a tray provided by contest officials onto the stage.” http://nationalyoyocontest.com/sports-freestyle-division/
This rule should answer your question. You can’t bring things like tennis balls or other props onto the stage for your performance. If you do, you will either be disqualified or the judges will refuse to score you for any actions involving those items.
