Have you ever chosen a bias arbitrarily? How'd it work out?

I usually choose my bias after watching several performances by the group and picking the one who stands out to me the most. Sometimes the decision isn't made until I've seen some variety content to get an idea of the personalities.

For Babymonster however, I was at a kpop store when Babymons7er had just come out and I wanted to get it. They only had the yg tag (member) versions so I asked my SO to help me choose which one i should get. we decided on the Ruka one based solely on the picture of her on the album. I basically decided then and there that she would be my bias and it turned out to be an amazing decision - I often bias the oldest members so that was cool, but she's also gorgeous, has amazing stage presence, and I find her funny/endearing in their bts videos and non-music content. I don't usually bias rappers, but I don't mind because she's a skilled rapper and dancer with undeniable star-quality.

Have you ever chosen a bias with very little info? Did they stay your bias when you got to know the group better?
