You can use seaplane bomber like zuiun but you can easily lose your zuiun plane ranks so be warn

the only reason i recomend seaplane fighter just so you can get at least air parity at boss node without loosing much planes

and don't forget the only way to go north route is to have 2 Kamikaze class DD and 1 of these DDs SatsukiFumizukiNagatsukiMinazuki
