Help! 30 stamina or 40 stamina Mihawk?

I was lucky enough to pull a g3 luffy and not sure which level of Mihawk I should do? here is what my crew looks like:

-Cpt: g3 luffy 42
-4* alvida 40
-4* arlong 45
-4* blamenco 25
-gp usopp 42

You can take down 40 stamina mihawk in 4 turns. Feel free to use the link in my signature to help calculate damage and such. Added 4* Blamenco to calculator for ya.

thank you!.... hope I can hit those perfects!
