1. All Kongou-class came with 41cm when you Kai'd them =w=;;

2. 35.6cm are still useful because they can be used for making Prototype 35.6cm Cannons which have good accuracy stats.

3. Your resources are very fine as long as you don't rush

4. Your ships and equipments are very good too.

You are all good to go. Just keep up the resource farming until the Event Day :)
