41cm and larger are considered "oversized" for the kongou Fast BBs, so you'd be taking a slight accuracy penalty in exchange for the larger firepower. Saw somebody mention in another thread that at most you'd lose about 6% accuracy, but I haven't seen any test data or tested it myself.

But it's still okay to do, especially if she's high level, since (from what I understand anyway) the accuracy that comes naturally through level ups helps to offset the penalty.
