IMO Girls that are able to do opening ASW with only two items, while having high firepower seems the best way to approach 7-1 ranking. The last slot can be filled with a gun to boost their surface combat ability.

...unfortunately, not many girls are able to do opening ASW with only two items outside marriage, and even fewer have high firepower (60+ firepower). Your girls kinda need to be above Lv. 95+ too to reach high base ASW. You most likely need a lot of Type 4 Passive Sonars.

(12.7cm HA-LM has +1 ASW which can work in a pinch...)
