1000pt List

We have a local tourney coming up, so i've got to design a new list. I've got a couple of ideas so far, but am looking for some constructive criticism.

Commander 145pts
- Relic Blade
- Storm Bolter

Tactical Squad 220pts
- Flamer
- Missile Launcher
- Power Weapon
- Rhino

Tactical Squad 205pts
- Flamer
- Missile Launcher
- Rhino

Tactical Squad 185pts
- Plasma Gun
- Plasma Cannon

And TWO of the following, either

Predator 120pts
- Autocannon
- 2x Lascannon

OR

Land Speeder 60pts
- Multi-melta

Land Speeder 60pts
- Multi-melta

OR

Vindicator 125pts
- Demolisher Cannon
- Seige Shield

Total:1000/1000pts

All i need to complete this list is the commander, i've been stuck using the AoBR captain for the time being, and the vindicator. But i'm going to be a linebreaker squadron soon so i'll be able to field any of the lists.

C&C welcome.
