Help!!! 2k tournament with pure de against cheese

I have a 2k tournament coming memorial weekend and I'm just running the true kin (no stupid allies for me). The tournament allows forgeworld stuff and other low units. I'm running msu with a little flexibility. The archon can jump between the medusas and trueborn depending on the army I'm facing. I know in order to win I will have to focus on the mission b/c the armies I'm going to be facing will be hard to take heads on (hopefully no kill points). I'm at 1971 and need to fill out my remaining points. Suggestions please.

Archon with blaster and webway

Medusa x4

Raider w/ sails

Trueborn x5
Blaster x4
Raider w/ DL and Sails


Warrior x5 w/ blaster (three of these)
Venom w/ sc

Warrior x5 w/ blaster (three of these)
Raider w/ DL and AS

Razorwings x2 w/ DL and SC

Reavers x6
Cluster caltrops x2

Ravager x3 w/ x3 DL

What about a couple heat lances on the reavers? Tank hunting, and with the S6 hammer of wrath attacks charging them, its a decent tank hunting unit in assault and shooting then.

I was thinking that since I have the spare points but I felt they would be jinking so I don't know if they would be worth it. I believe I would go with that.
