1. 35.6cm is very cheap to upgrade (in terms of screws you can do it for free if you take your time).

2. 35.6cm is Kongou class' fit gun. They get bonuses for using it. They also get penalties for using larger calibre guns (41cm, 46cm, etc). They can also use 38cms kais but they are much harder to obtain than 35.6cms.
