You can include the Heavy Midde route that uses heavy fleet B-C-F-H-M for players don't have strong CA(V)s.

Also note that you can get AS pre-final with just Kaga with max skilled reppuus on her 20/20/46 slot prefinal on the boss. You can also get AS prefinal with max skilled reppuus on 20/20/12 slots with a CA(V) or BB(V) with a zuiun (or varient), assuming all the zuiuns dont get shot down (dangerous on CA(V)s especially Mogami class).

If you want to use a heavy fleet with just 1 CV, you can get AS on H with max skilled reppuus on Kaga's 20/20/46 slot and a fusou kai2 with a max skilled zuiun M12 on the 23 slot.

And finally, theres a way to take subs to the boss for subtanking. Im not exactly sure how it works, but players can try to do it to keep 4-5 boss's aggro on the sub.
