Before going over your suggestions, Paradox, I'd like to correct an error. The list above would be 505 points, not 500 points. I mixed stuff up when typing the above, and the actual list I meant to type is more as follows:
Chaos Lord w/ Power weapon & Combi-weapon.
Chaos Space Marines #1, Aspiring Champion w/ Power weapon, Meltagun, Chaos Rhino.
Chaos Space Marines #2, Aspiring Champion, Meltagun, Chaos Rhino.
Chaos Predator w/ Heavy bolters.
(Internal ref.: variant #3)
That being said...If I drop a single Meltagun and the Lord's Combi-weapon, I'd have 20 points left; not enough for a Powerfist.
Since neither squad has enough models to field a Missile launcher, Autocannon, Heavy bolter or a Lascannon, I've got a few options left:
- Twin-linked bolter for either or both of the Champions
- Combi-weapon for either or both of the Champions
- Plasma pistol for either Champion
- Melta bombs for either or both of the Champions
- Chaos Glory for either or both of the Squads
- Plasma gun for either Squad
- Flamer for either or both of the Squads
Obviously, options increase if I drop both Meltaguns
Thinking about it, if I won't keep the above (corrected) list, I'd probably go as far as dropping both Meltaguns, giving one Champion a Power weapon, the other a Power fist and my Lord Melta Bombs, next to his Power weapon, since dropping a single Meltagun and the Combi-weapon doesn't open up options I like.
