Considering Incubi

I've been reading up on Incubi recently. It seems they're about the biggest gamble in the game since any sensible opponent will try to down them ASAP. Well, duh.
The upside to these guys is the immense melee bite they bring to the table, and with the attaches Archons more than makes up for their bullet-magnet status. All my eggs in one basket? Well, yes. Should I hit you with that basket, however, I'll break your face.
The Klaivex, however, are probably not worth the cost of almost two Incibi each.

The army I've written up still has the added threat of the forthcoming Wych assault. These girls (and guys) are more than capable close combat opponents.

Fourteen Dark Lances are capable of offing vehicles and mangling dangerous close combat opponents. The problem remains with the army being a glass cannon, and amassed anti-armor fire will quickly strip my evil warriors of their rides.

Without further ado, here's the revised army list:

HQ

-Archon with Combat Drugs, Huskblade, & Shadowfield
-Archon with Combat Drugs, Huskblade, & Shadowfield

Elites

-7x Incubi; Raider with Flickerfield
-7x Incubi; Raider with Flickerfield

Troops

-10x Kabalite Warriors with Dark Lance; Raider with Flickerfield
-10x Kabalite Warriors with Dark Lance; Raider with Flickerfield
-10x Wyches; Hekatrix with Phantasm Grenade Launcher & Agoniser; Raider with Flickerfield
-10x Wyches; Hekatrix with Phantasm Grenade Launcher & Agoniser; Raider with Flickerfield

Heavy Support

-Ravager with Flickerfield
-Ravager with Flickerfield

I'm thinking that this army has a more rounded feel, and with the Archon's  Combat Drugs he'll have a lot more of a combat punch (to the point he may not even need the assistance of the Incubi). The more amassed Incubi squads should be more survivable with their Space Marine armor save (as well as the fact that there are now seven of them).

Another thought, but another concern- Do I have enough Dark Lances?
