What I did was:
Aideen/Dew
Aira/Holyn
Lachesis wasn't paired.
Sylvia/Levin
Killed Fury as an enemy because I didn't know she could be recruited.
Tiltyu wasn't paired.
Bridgid got killed by the pirate attack right after she joined.
I've never heard Aideen/Dew is good: is it?
Aira/Holyn made Skasaha OK but Lackche almost unstoppable.
Lachesis didn't matter because I didn't use Tristan and Janne got killed in chapter 7 because Fin was level 1.
Holsety went to wate because Corple never promoted.
Femina wasn't too bad and Hawk was pretty good.
I never used Amid and didn't even recruit Linda.
Daisy was only used to give Shannan the Balmung and for money and I didn't recruit Asaello
