^yeah aren't the number groups the only ones that admits to such a policy exists? At least I never seen other groups talk about it.

From the Idol Express thingy I went to yesterday I really liked アキシブ project, 絶叫する60度, CANDY GO!GO!, READY TO KISS and 夢標 (elfloat) - there was some kind of vote for the event and アキシブ project won, not sure if it was just this event or overall for a series of events though (and I got to see Tokyo Tower close up since it was right next to it).
I didn't know of CANDY GO!GO! and READY TO KISS before since I didn't realize that they were kinda rock, I assumed from the names that it would be some generic J-POP!!!
3000 Yen well spent including drink ticket.
