If you want traditional judges, get traditional judges who have danced live Bhangra. Many of the judges posted have done traditional Bhangra, but i wouldn't call them proper traditional judges because they have done Bhangra in the past 7-8 years. Since then till now, Bhangra is still "evolving". We're so used to seeing teams doing gimmicks, being creative, trying to compete with the rest of the teams just because of the creativity fad. Even if you are called traditional today, you really aren't. Judges' mind is set on seeing what everyone does today. They already know what to expect from the teams performing, which is being creative, gimmicks, blah and blah.
