It's all up to preference really. Depends on what CVL you use, what level she is (attack stat) and how big her slots etc..

And also (potentially) sinking 3 ships in the initial airstrike might cause your FL not being able to attack twice to really secure MVP (sometimes not even once).

Finally 62 fighter bombers are more rare than 99's so that might be an "issue" for some.
