Dark Eldar light cruisers

[ArtificerArmour]

Well, since the dark eldar lack a few types of ships (only having an escort and cruiser) I decided to throw my hat into the ring and "design" two light cruisers. This means they have a cruiser under 200 points and can sensibly take part in the cruiser clash scenario. Let me know what you think.

Dark Eldar SIN* class light cruiser - 130pts

TYPE/HITS: Cruiser/4
SPEED: 40cm
TURNS: 90
SHIELDS: Shadowfield
ARMOUR: 4+
Turrets: n/A

Armaments:
Keel Phantom lance, range 30 cm, strength 2, Front arc
Keel Torpedoes, speed 30cm, strength 4, Front arc

Dark Eldar REAVER class light cruiser - 150pts

TYPE/HITS: Cruiser/4
SPEED: 40cm
TURNS: 90
SHIELDS: Shadowfield
ARMOUR: 4+
Turrets: n/A

Armaments:
Keel weapons battery, strength 6, range 30cm, front arc.

In addition, the cruiser may pick ONE of the following armaments for no extra cost
Keel weapons battery, strength 2, range 30, front arc
Keel phantom lance, strength 2, range 30, front arc
Keel torpedoes, strength 2, speed 30, front arc
Keel impaler, strength 1, range 30, front arc

Obviously, all usual cruiser options apply including a mimic engine for 40 pts. I roughly based them on the Eldar light cruiser equivelants. I have no idea how to convert them though.

Anyway, C&C welcome.
