it shouldn't be any skinnier than a kusari destroyer, and it'll have more surface area from the side than the kusari Dessie. it's based off the BH fighter designs, so it will be skinny....as a destroyer anyway. the bigger ships will become wider
remember this thing only has 8 turrets. which is not alot compared to another skinny model, the Outcast Dessie that has 12. that being said, i wouldn't doubt that some nerfing of agility might come but i'm not sure...i've never flown the BH destroyer to know how nimble it is.
as for extra fins, like i said before i'll be building off of this design to create the other, bigger cap ships. each increasing in size with more fins and so on
