Small difference.

Now, you can get few more experts or vets on your pilots, or using one slot for a seaman is up to you.

what supports you recommend? with a CV6 you have 3 slots free. 2 E slots and a support slot.

It is a user preference.

I can't really decide which you want.

Some people use repair, engies, restore, sonar, seaman.
Some people also like to have equipp with gunners if possible so they can defend themselves from sub and ship.

Of the most loaded subject lines of all time.

Oh CV not CA, and SS goes without saying.
