TB strong point as following :

- Better sight range
- Easy to attack sub and AA Ship.
- It good more to sink something CV's have local fighter already.

TBs so important also i think~ :)

I started it out with 1 TB, but found it much more usefull for 3-3 fighter/DB
Everybody has bulge which makes it nearly useless to send out TBs and if SS scare you
mount HH

"So at what level will they become AAW immune?"

Assuming you are BVE, 100 vets, full experts as well as 12+, it would be near 90s to mid 90s.

Well, this is what you can do with TBs

I wouldn't use them, 7 of them really don't do anything to the Bulge you need 10-14 to
break through if you dont' get shot down by FP's, AA, and manage to not miss.

Db's far more effetive when i use them, maximum damage, lots of tonages sunk, and its easy
to NOT miss.

Little ship are hard to touch and bb joke wenn you touch them ... :/
Currently i am just leveling my 2 torp, not using them until they are high level enough.
Whit low level pilot db are clairy easier to do something whit. Monday i have done "7" of
damage to a bb , whit 2 torpedos hit.

Forming them up are easy just launch in revers order i.e insteand of pilots 1 then 2
then 3 go pilot 3 , 2 ,1

and spam click once they all come out
should do it just fine

and

TB>DB

Also, TBs are much better scouts than DBs. At the beginning of the game, I quickly
load a couple of TBs, attack any SS on the surface and then use them as scouts
while loading fighters or DBs. I prefer to keep all types on my ships. Its just a
matter of knowing when and how to use them best.

So at what level will they become AAW immune?

I seen some of those British TBs, and those things are insane. Although forming them into
a nice packed little group would be hard without the manual DB function.

TBs also take less space, are faster, and do much more damage to an unbulged target than
the same amount of DBs do. They provide great fire support for submarines as a bulge
check and can force ships to enter firing range of your teammates through
counter-steering. My TBs aren't AAW immune yet, but they're pretty close.
