1k raid list

My friend and I are starting a Campaign. The premise is that the Dark Eldar have just finished raiding the planet when an Ork Asteroid crashes into the planet. Battles ensue.

For the first battle we're doing 1k points. The restrictions are No Heavy Support and no Flyers. So here's what I put together.

HQ
Baron

Troops
10 Warriors (1 w/ cannon) in a Raider (Flicker Field)
10 Warriors (1 w/cannon) in a Raider (Flicker Field)
14 Hellions
3 Grotesques (1 with Liquifier Gun)
1 Hammy (liquifier gun)
6 Reavers (two with heat lances)

Now here's the thing. I know that he runs troop heavy and only really has one trukk with his Warlord usually. Are the Heat Lances a waste in this instance?

I've got lots of mobility and one group that can do serious harm if given the opportunity.

Opinions welcome!

If he's troop heavy I'd consider Dissies on the Raiders and keep the HLs just in case you do need AT.
