Late showing females?

Hey everyone!
Is there anything positive about females that take forever to show their sex?
I know that's very vague, but it's just a general qurstion...

Positive? Not necessarily, unless it's a great strain with high thc percentage.

Gotcha.
I've heard of some breeders using late showing males when determining which male to use for breeding... wasn't sure if there was something special about the late showing ones...
