2k Dark Eldar with under 20 KP

So far the major vulnerability in my Dark Eldar lists have been the number of Kill Points I give up.  I'd really like to get my 2,000 point list under 20, and closer to the 17 or 18 mark.  This means the small Wrack squads are likely out.  I'm going to try a Wych-style theme so the Duke and Baron are in.  Lelith is a possibility as well, but since the Duke benefits all Wych and Hellion units, I'm gonna try him out first. 

Cult Army (Version 1.0):

Duke - 150
Baron - 105

10 Hellions (Helliarch; Stunclaw) - 195
10 Hellions (Helliarch; Stunclaw) - 195
10 Wyches (Raider: FF; 2 Hydra Gauntlets, Hekatrix; Agonizer, PGL)- 230
9 Wyches (Raider; FF; Hekatrix; Agonizer, PGL)- 200
10 Warriors (Splinter Cannon, Syrabite- 110)

3 Trueborn (Venom +SC; 3 Blaster) - 146
3 Trueborn (Venom +SC; 3 Blaster) - 146
3 Trueborn (Venom +SC; 3 Blaster) - 146

Ravager (FF, NS) - 125
Ravager (FF, NS) - 125
Ravager (FF, NS) - 125

Total: 1,998
18 KP (Success!)

The Duke starts with the Warriors then hops on the Wyches Raider.  The Ravagers and Trueborn wreck vehicles and transports, while the Wyches and Hellions work in groups mopping up what spills out.  I might have to add in some other CC elements (Incubi, Beastmasters, etc...) to replace the Trueborn.  I have finals this week so no gaming.  This means the list might (99% sure it will) evolve from now til next Monday.

My biggest concern?  The Hellions.  Everyone I talk to is gaga about this unit but I don't quite see it.  They seem way too fragile to make an effective close combat unit.  I'm hoping that combining them with Wyches will help a bit.  Has anyone experimented with the Baron and Hellions? Stunclaws?  Successes?  Failures?  Let me know about it.
