Eh, your other choice is spending a lot of screws (or resources if ranking) for 15.2cm Kai which trades firepower for accuracy, 15.5cm main gun which is good enough but still inferior, or 20.3cm variants.

Besides, there is Akashi's improvement. Even this guide above listed OTO 152mm for one of CLT's setup. ( .__.)
