Dual Razorwing, or Razorwing and Void Raven?

As the title says. I'm definitely fielding 1 ravager and 1 razorwing in my 1500 point list, and I have a second flier to build. Problem is, I can't seem to decide whether to rock a second razorwing or throw in a void raven. The raven gives a pair of S9 lances and a singularly vicious one-shot mine, but I'm wondering whether the 4 missiles will be better more often.

Well, it depends on your personal gaming area. Against which are armies are you playing and which problems do you encounter during the battle?
If your enemies field large numbers of infantry and ground vehicle, take the razorwing. But if you encounter a lot of flyers take the Void Raven, because the bomber is the better AA fighter (because we can't use missiles in Aircombat).

Personally I believe that Dark Eldar already have enough AI so the Voidraven is a better option. That being said, the times I have used it its gotten shot down very quickly.

Dual Razor was my plan, lances and stock missiles

I'd still say putting lances on a razorwing is a waste of time, Jack of all trades master of none

But I consider the missile "enough" anti infantry without the dizzies.
But its an open question.
