Reading LK's BB guide should be enough info on ideal setups for getting to BB6. Try that first and re-ask if thats not enough information.

Main issue with 6/2, is short of 2 elite reps vet capped, I dont think they hit the rep cap or get close to it.

with 3 x 229 vets elites on my KM I didnt reach it.

Having the AA/HH option with USN is always nice, but in the long run I prefer running full support for USN. Especially since many ship lose speed running AA, such as monty.

6/4 makes for quite a nice BB crew, and its doable to hit the rep cap if you shoot a bit of money in your reps, still. Otherwise makes for a decent rep rate still.

I am running 2 main gunners, 1 scout, 1 restorer, 4 reps, and 5 engies on my Nebby. If you play it right, you won't need a second set of gunners. But then again, it is a preference. There is nothing wrong with 2 sets of gunners, i just find them useless for US cause of lack of AA range for a BB. The restorer helps put out fires quicker so you can repair faster, not the repair rate but how long it takes you to start repairing. I honestly don't know how to figure out the rep caps or speed caps or anything like that, but I do know that it works. I average 200K in my Nebby per game and can take more of a pounding compared to other Nebby's I have seen, not all.

I run 2x main gunner, 6x Engy, 4 x rep, 1x scout. Works well for me

I'd rather ruin someone day than let a new player take wrong advice.

Note that I never personally hit a guy. But I do tear apart unaccurate post. Sorry if people like their post.

It's really whatever you like, I personally like 7/3.

I'm not going to bother with that statement.

Suffice to say my Fail-o-meter is now taking pills to cure its burn out.
