NEVER sell them... they're way better used to buff previous copies or used in a 2nd team

I'm going to have to disagree with this slightly, If your 1st copy has 5/4 skill/equip then feel free to sell any additional copies you get. I know it sounds far fetched but quite a few of us have had 5* stalkers and gotten more than required to max 1 girl.
