2000pt Betastrike List

I'm getting back into WH and WH40k and plan on building the list I always planned on doing, I loved the tactical usage and advantage of gunboats and I actually like new reavers as a melee entanglement. Here's the list, I'm using a Realspace Raider Detachment with 2,000pt

HQ;
Archon - Shadowfield, Armour of Misery, Soultrap, Agoniser

Elite:
Trueborne Boat
    - 7x Kabalite Trueborne
    - 2x Kabalite Trueborne w/ Splinter Cannon
    - Raider w/ Nightshield and Splinter Racks

Troop:
4x Gunboats
    - 9x Kabalite Warriors
    - 1x Kabalite Warrior w/ Splinter Cannon
    - Raider w/ Nightshield and Splinter Racks

Fast Attack:
Scourge
    - 4x Scourges w/ Dark Lances
    - 1x Scourge

x2 HWB Scourge
    -  4x Scourge w/ Haywire Blasters
    - 1x Scourge

x2 Reavers
    -  4x Reavers
    - 2x Reavers w/ Caltrops

Heavy Support
2x Ravagers w/ 3 Dark Lances and Nightshields

--------------------------------------------------------
The total comes to 2001pts the general tactic is to place onto field the Reavers, Ravagers, and Dark Lance scourges. That gives me 10 DL shots at the beginning, and Reavers to begin outflanking. The gunboats are going to come in on turn 2 to tear up the enemy, most often always jinking. I'm just getting back into WH40k and am wondering how well this list will hold up.

You can't have 2 caltrops in a four dude squad.
And why dark lances on scourges? You're basically sacrificing your mobility.

Other than that, it looks fine. Maybe drop the Splinter Cannon on the true born and add Blaster. But they'll become high priority targets. So it's up to you.

It's a total unit of 6, there's 4 stock and 2 with caltrops. I went with DL as I wanted to get more of a sniping group in the early game and wanted more firing DL outside of the Ravagers,

With the number of flyers increasing in all the codexes, I'm beginning to believe dark lance scourges are becoming viable. You try to find a nice cover zone for them, with good line of sight and when there is nothing to shoot at, you move them to another cover zone, snap-shot firing at flyers in the process.
