They're definitely stronger as a group, but u know it won't last forever since someone is always graduating and new members and such. Even though i love them all. i hate to admit that the two that would best survive in the music world as solo artist as or right now would be Ai Takahashi and Miki Fujimoto. although Koharu Kusumi is doing well i think. Miki had been a soloist before so she have the experience and such, so she'll be just fine i think. Ai have the talent and the looks but it would be hard for her in the beginning, she is just too sweet, she'll be gobbled up out there in the real world. Same goes for all of them. And i think that for those who doesn't seem to actually survive as a soloist should probably be placed in a duo/group(aka Viyuuden or W), i think it's better that way. It's a scary world. But as long as they supporters, i think they'll be fine. I think it's best for know that they try to experiment on solo projects or sub projects of that sort. u know like starred in a movie or jdorama(or anime), host a talk show, have a radio show, etc. u know the usual like most of them already do, especially the graduated members. The point is so that they can get more exposure and while still being a singer, able to do other stuff to show off their talent and just go from there. Anyway i hope them all the best!
