A Little Question about Italian CA

Good evening,

I have a question about the difference between the Trento-Class and the Zara-Class? In the navypedia you have written the Zara-Class have a improfment in the Main-Ari to the Older Trento-Class! Ok, the Zara has more Hullpoints and more Amor, but the Zara is slower, has no Torpedos and no better Second Ari and the Main-Thing the Main-Ari is the same as Main from Trento on the Sheet. The Trento cost 34 Splints and the Zara 38, is this correct?

Well, an increase in armor + HP makes them a very hard nut to crack for any other cruiser, so the increase in costs is more than the decrease for the loss of torpedoes.
