I always wondered if there ever has been a time in Yoyo history that someone suggested or it ever happened at a national or world contest, I see it’s used a lot in smaller contests like state ones, but I’ve never seen any perform national or world routines with black lights. Maybe it could be a special request, it really all depends I’m not an expert.
Some thoughts i have to maybe why they don’t do it is maybe the string won’t have depth when it glows so it makes it harder to judge (non judging exclusions being alternative freestyles) or if it’s genuinely not a good idea to perform in general shifting the focus away from intricacy to flashy who knows.
What are your thoughts!
