since i was born and rasied outside of india, i'd have to go with the nri team, just cuz i can relate to it the most. but i think i'd want to equally support Uttar ke Putthar, because my family's from north india, and its the only part of india i've visited and am sorta familiar with. lol
but i agree with iiHEARTyu-x0, it is about the talent. and i think whoever performs the best should win! so good luck to all the zones!
