My options for the 9 models:
8 Incubi (maybe Klaivex for duels or for the Massacre power) and a Haemy.Pros:
1- Kills a Lot (fear me, TEQs!!)
2- 3+ / Fnp unit.
3- You can use the older model (I love the old Incubi with robes)
Cons:
1- No Grenades
2- Overkill (well, unless you charge units in terrain... then you'll need the numbers)
9 Harlequins(+equip and options)Pros:
1- If the Dais goes down (and when you annihilate enemy units in your turn), you can benefit from Veil if you pay the points (getting grenades also).
2- Fusion pistols give more versatility than Incubi once you disembark.
3- You can have up to 3 characters (apart from Vect) for duelling.
4- Invulnerable saves in h2h, so you can fight the big guys.
5?- Oh, and the FUN! (clowns!!)
Cons:
1- The Dais does not benefit from the Veil and,
2- This unit is not cheap at all (at least you don't pay for a heamy).
9 Trueborn with Shard CarbinesPros
1- Vect's Preferred Enemy makes this a really good shoty unit (better than only adding Sliscus to TB)
2- If you add the Dais, then you got a though and fast as hell boat that can destroy any vehicle, full of bloody Dark Eldar elite warriors that will shoot down any living creature in the Galaxy, without touching the ground. Cool.
Cons
1- Not really of a combat unit, but hey noblemen don't kill foxes with swords. This is a hunting, just for the fun and the trophies
2- You need to be 18" away from your enemy before shooting, and more than that afterwards, so they can't charge you. If you're against a fast unit, kill them fast, or send the dogs (beasts, hellions, wyches or incubi) to finish the work.
I really like the last option, I will try it some time...
There are others...
Kabalite Warriors: not that killy, better use them with Splinter Racks and maybe Sliscus, but not Vect (unless on foot, but that's another story...)
Wracks: They just won't shine, there are better options.
Wyches/Bloodbrides: The girls can protect Vect, but that won't be fun. On the other hand, he will help despatching MEQs, but again Wyches don't want to end the combat, so you should go against enemies that are either fearless or really powerful.
Archon's Court: well, this is an option after all... you don't need an haemy because you can get FnP in Ur'Ghuls and Sliths, but a Liquifer gun can come in handy... then I'd pay for the 2 Medhusae everytime, so if someone charges the Dais, they'll be mind-toasted and digested to man puree. Disembark in the middle of the enemy lines to kill any opposition in hand to hand. Have fun, shoot and charge... because being the Lord of Commorragh you need to relax from time to time.
Hope it helps!!
