500 point Night Lords list

So my main goal for making this army is to create a fun, fluffy, and semi-competitive list that I can use in the upcoming escalation league at my local game store. I will be using the Blood Angels codex because I think that it displays a Pre-Heresy Night Lords army better than the regular Space Marine codex or the Chaos Space Marine codex, Plus this way I can get a company command squad with jump packs :). So here's the 2 500 point lists that I'm debating on right now:

HQ:

Captain Taron: 155pts

-2xLightning Claws

-Jump Pack

Troop:

Assault Squad Reevax: 220pts

-10xMarines

-Power Fist

-Flamer

Heavy Support:

Dreadnaught Veston: 125pts

-Twin-Linked Autocannon

-Blood Fist with built-in Heavy Flamer

And the other one is:

HQ:

Captain Taron: 155pts

-2xLightning Claws

-Jump Pack

Troop:

Assault Squad Reevax: 220pts

-10xMarines

-Power Fist

-Flamer

Fast Attack:

Bike Squad Shrax: 125pts

-4xBikes

-Meltagun

It all really depends on what the final rules will be in the escalation league, but both should be decent lists either way. I will also be trying to write up fluff for the army, thus why every squad has a name after the sergeant that leads them. Still trying to work out what names work out with Night Lords. I am the Night!
