1500 tourny list

Hey guys, I have a tournament coming up and want to take my Dark eldar into it and would like some help tweeking my list!

HQ
Archon
-husk blade
-shadow field
-webway
-animus vitae(thinking of dropping this for a blast pistol)

Haemy(covens supp)
-hex rifle
-scissor hand
-Nightmare Doll
-webway

Troops

2x 10 kabalites
-Splinter Canon

2x raiders
- both dark lances
-nightshields
-splinter racks

2x 5 Wracks(I know they're not troops but live with it)
-ossefactor
2x Venoms
-splinter canon
-nightshields
*these two units of wracks are in a scalpel squadron)

Elites
4 Incubi(definitely swapping these out)
-klaivex

Fast
5 scourges*archon maybe here*
-4 blasters

Heavy
Talos
-chain flails

Chronos
-spirit probe
*these big guys go with the Haemy in the Dark Artisan*

Voidraven Bomber
-void lances


I was thinking of dropping the kabalites down to 5 man squads with blasters in a venom, and the incubi for either a ravager or another flier. I know wracks aren't troops. Since the archon is with the scourges would it be wise to give him dual blast pistols instead since they will be tank hunting for the most part? The Haemy is my Warlord.
