Does "favorite former unit" include groups like Berryz? It might be a matter of wording, but I thought unit more referred to stuff like GAM, DEF.DIVA (I think...) or, to an extent, Buono (and sub-units being Minimoni and Petitmoni, shuffle units being the yearly ones, etc), where members are primarily involved/associated with a main group but not the same group, making it not a sub unit? Maybe "Favorite Former Group" as well where T&C Bomber, Berryz, and other groups would go? Also, maybe Favorite Morning Musume Sister Group, including Country Musume, Coconuts Musume, Icecreamusume, etc, if those qualify?
I personally really like the idea of making a Berryz category in Singles at least, their last one isn't even a year old and they were such a big part of Hello!Pro.
Favorite Soloist sounds good too, and WB's suggestions seem sound, definitely! What about "Best H!P Dancer" and "Best Former H!P Dancer"? Also, are we going to branch into the realm of "Least Favorite" and "Worst" items? I'd hate to include members into that and turn it into a member bashing spree, but stuff like "Worst Outfit" and "Least Favorite Single" seem safe enough. And how about "Saddest Graduation"?
