We had....
PLD/WAR
DRK/WAR
WAR/WHM
WHM/BLM
BLM/WHM
BRD/WHM
Basically, we just beat them straight up

A few advices:
1. The Bard must turn off damage messages on the log.
2. All mages must concentrate on curing the bard. Bring more yagudo drinks/hi ethers just in case you need them. If you bought extra you can always sell them back.
3. Must bash the black mandragora when it casts flood!
4. Bard must sing Ballad + Pian3. All mandragoras have a wide area sleep ability.
5. Mandragoras have a regen ability. Try to make them sleep before they do it.
Good luck
PS. We just beat the 99 coin BCNM too (a different PT)

at Yughott.
(Oh yeah, if you want to fight BCNM, better to do it before the next version up because of the weakening of Bard...)
