1850pts Tourny List

Looking for some last minute feedback on my tourny list for tomorrow. I have been switching a few things around here and there and Have finally found a list that seems pretty well balanced.

-Baron
-Duke (Warlord)

Wracks x3 - 95pts
Venom SC x2

Wyches x7 w/HWG (Eventually the duke will go here) - 149pts
Raider w/dissie and enhanced athersails

Hellions x14 (for the baron) -224pts

Warriors x5 w/blaster -130pts
Venom SC x2 Grisly trophies

Warriors x5 w/blaster -135pts
Venom SC x2 with Night Shields

Reavers x6 w/ 2 heatlances -171pts
Arena champ w/venom blade

Ravager w/3 DL -115pts
Nightshields
Ravager w/3 DL -115pts
Nightshields

Voidraven Bomber -155pts

Total is 1850 on the dot.

I have really enjoyed running the Baron hellion gang. Main thing I was trying to do was limit the hellion tax (haem with wracks) and capitalize on the use of combat drugs. I have really enjoyed adding the unit of wyches up to this point as they provide a great distraction unit that allows me more turns of shooting. Depending on warlord trait rolls and combat drugs I may use the Duke's ability to deepstrike in some venoms for close vehicle shots and good positioning on killing troops. Wracks are there for a venom and cheap pain token for the hellions ( a must have to survive )
Reavers seem to eventually get into combat so I thought I would add in the arena champ for some added punch. Depending on combat drug rolls this unit could become really good. But this is also where I would probably cut points from first as well.
Anyways let me know what you think... Anything you would change?

only thing I see is the Duke having to deploy with a unit of your kabalite warriors to start being a bit of a pain in the vexator mask (lol). You may be better off with an archon or haemy combo.
