Decided against upping the speed, instead used the gains from removal of the armour torwards increased range and stowage. Also modified the secondary/AA armament. Now the hull strength is at 1.00 as well.
Forgot to mention that this ship will carry an a/c and catapult...
Also, the 155mm guns will be lined down to 6", for Treaty purposes.
