1,500 points v. Dark Angels

Hey! So I'm a fairly new Dark Eldar player, and complicating this battle is two facts:

1) This is my first sixth edition battle
2) I've never played against Dark Angels...

Griping aside, I've decided to take a departure from the gunboat Warriors that I typically use and instead deploy them in larger squads. I plan to attach each of the Haemonculi to a squad of Warriors, and was hoping to use the Wyches for anti-tank (in addition to the Dark Lance Ravager of course).
To be honest, I'm not quite sure what my opponent will be using; he has the luxury of having quite a large selection to choose from. I know he has both Deathwing and Ravenwing elements, as well as a large amount of armor and a full battle company. Great.
Without further ado...

Any and all of feedback and advice is appreciated! I'm really just trying to learn this all as quickly as possible.
As a side note, I have two more Haemonculi, ten more Wyches, nine Reaver Jetbikes, and a Beastmaster (with two Razorwing Flocks) in my collection, so recommending a unit not included in the list above probably would not help as much...
Thanks in advance!

Edit: Anyone? xD

Please dont double post to bump up your topic. -Your Friendly Neighborhood Mod SR-

First off the only viable build for DA are Ravenwing or Deathwing, as anything of their basic army is completely overpriced. So expect to see termies/bikes/speeders.

Now that you know what you are probably going to face, take a look at your list and think what would work against that.

First thing I am not a fan of 20 man warrior blobs. What do they do that a venom couldnt do better, for cheaper? On top of that whats the purpose of the PGL on the Sybarite, as they are only good if you want to assault, and you should never be assaulting...

As for the wyches, decent, but what is their power weapon type???

I would keep your 2nd ravager as a DL ravager. If you really want some more dissies, switch the wych raiders to dissies
