Guys should I get bina or skip for odette?

I'm basically sitting at 77 pity with a guarantee but now I'm having second thoughts. I'm f2p...I already have flins, ineffa and c6 aino...I was planning to get bina but odette seems necessary for stellar meta and I already have sandrone.

Is columbina still worth it? Should I double down on her or wait a couple days for odette? Cuz if I get bina now I may not be able to get odette for sandrone.
