What's the most optimal party setup for Titan HM?

[Sebyos]

1 tank, 5 dps and 2 healers.

Jobs don't matter, this is Titan and it's not hard no matter the composition as long as people can avoid bad stuff.

Optimal and viable are different things, you can down titan fairly easily with any setup, Ive done it with one healer, however if your trying to kill it as fast as possible, I would take 1 melee, and stack 4 SUM/BRD/BLM as your dps

Oh boy, here comes the cookie cutter parties! Yayyyy, let's all do the same thing! Yayyyyy!

1 PLD
1 WHM
1 SCH
2 Melees
2 SMN
1 BRD

Pretty much the best setup I can think of.
