akitsuki in normal version is as slow as a kagero so the kai form gives a better engine, better torps(type 90 X5), better gun space and more displacement becuz you'll need it most when ur displacement is going to be maxed out cause of ur crew since the body is already half the weight of its full displacement. the sacrifice is 200 DP which isnt much so yes remodel it. its very cheap fee of 7500. not much losses as its a better ship to grind your way to mogami. btw, agano is a bad ship if its your fisrt time using it cause you'd be using the dual 6" which are not for agano and its a hulking taget. if you want, try agano when you get 7.9"B. though they're not the best but they can outrange most cls and can pack a punch if they hit. becuz agano carries such high calibre guns at the cl1 range. NEVER go close using an agano cause most of your shots are harder hit up close(unless broadsiding) and your rld of guns will buy even more time for other fast rld dds or cls to take advantage of you. hint: high calibre guns are actaully easier and more accurate to hit if you maximize your range.

I'm too used to Fubu turning...all that twing 5 months back still haunts me once in a while.

still sucks? it's only out-turned by the Fubuki in terms of national DDs!

displacement, not durability.

Yes, Kai has less HP but it can fit more stuff and it is faster, better turn rate (still sucks), better aiming control, everything that makes it a great gunship...until you can ues DD3 ships.

Well the Akitsuki actually has 7200 vs. the kai which has 7000, so its a small downgrade in that sense. But that is minor when contrasted with the numerous benefits.

The kai has a cheaper full repair cost at 336 vs. the normal 360.
The kai has more practical displacement, 1814 vs. the normal 1611.
The kai has better turning force, 33 vs. the normal 30.
The kai has a better fcs, 45 vs. the normal 40.
The kai has a larger power plant meaning it can use the DD3 engine instead of the DD2.
The kai has the larger T slot, 38 vs. the normal 32.

Theres a few other minor differences but I think that covers the main ones.

get it because it allows you to get dd engine 3, better fire control, 200 more displacement to use, and also adds turning force to avoid those nasty torps :D
