Ek Mein aur Ek tu-Voting

Rightfully, it should be best pair, since that is what the contest is for... But I can just see a really good male singer getting stuck with an average female singer or vice-versa. Then what happens? Justice isn't really done to anyone.

Especially if they are bringing back C2005 contestants, other than Nihira, I wasn't impressed with anyone else (
in the girls) in the top 12.

I don't get the whole idea of best couple anyway. If the contestants themselves chose their own partner, that would make sense, but not if they get assigned a partner by GS or whoever.
