I was thinking about making a nice blockshooting KM AA:
1. Using 2 x Elite RLD Sailors (11 Acc / 13 Rld on base) + giving them Boost
2. Keep as 'Arm.Sailors' to 55 lvl and then class them to 'AA Gunners'. Why 55 lvl ? -> for not loosing ACC ability and for sooner RLD cap than classing them on 60 lvl (richard advises to class them on 50 lvl).
3. Because of classing to RF and CRF doesn't give any bonuses to RLD growth and only decreases ACC I would keep them as 'AA Gunners' to 70-80 lvl. Then to use '42 lvl x2 5"/61 KM 40 A' on Bismarck/O Pro 2 (and higher tier BB's) I would class them on RF Gunners (lets say classing 'AA Gunners' to RF on 80 lvl) ... without classing to CRF ... I don't see any meaning to class KM AA gunners as CRF, you gain nothing (except 'not working' AAW stat '+2') and only loose ACC growth ('-4') ...
What do you think about this ppl ? This is interesting to check.
