Dark Eldar Air Force 1850

Hi guys.

I've being toying with the idea of making a Dark Eldar Air Force. I put together an army list and I thought I'd put it on here. I've only got one Razorwing, the Archon, 2 venoms, Kabalites, Wyches and Raider so far, so it's very up for adjustment. I do have other models, but those are the only ones from this list.

I'd like to work in a Scalpel Squadron at some point for null deployment, but I don't know what I'd take out. My meta has a long of Knights and there's a Tau player with a Riptide and some forgeworld stuff. Obviously there's a lot of Space Marines around. Both troops heavy and vehicle heavy Space Marines are common.

Any advice would be really appreciated.
