I know Zoo TV took balls as everyone expected them to be a rock/countryish band.
PopMart took things to a whole new level and had the most balls, you can really tell they are enjoying it and things like HMTMKMKM are so original and cool.
Saying that The Fly and Mr. Macfisto took balls, a lot of balls but I think U2 take themselves too seriously these days and are afraid to embarrass themselves, I can't imagine Mr. MacFisto making an appearance again....
I still can't decide between them now...
