4-2 with 5 to 6 Lv50+ subs is one of the cheapest ways to clear Bw6.

You can also rotate 4-2 with Lv.60+ 2DD, 2~3CLT and 1~2CL, which also ends up being relatively cheap to field.

The all sub fleet actually has a slightly higher chance of getting to the boss at 4-2, because going through that whirlpool ends up giving you two chances to reach the boss node.
