Space Marines: Twilight Ravens - Ironing Out Flyers

Warhammer 40,000 - As I continue to put together potential lists from my vast collection of Space Marines, I’m slightly torn. Most of 8th Edition I’ve been building list to maximize the amount of Command Points I have to take advantage of Stratagems. Most armies I’ve played rely pretty heavily on the tricks you can pull off with CP and don’t really function without at least a battalion. Iron Hands seem to have access to all the cool stuff and their traits make vehicles pretty self sufficient. As such I started kicking around this idea.

SPEARHEAD

HQ - Techmarine on Bike: Conversion beamer, Power fist, Storm Bolter, Student of History, The Gorgon's Chain, Twin Boltgun, Warlord
TROOP - 5x Intercessors: Stalker Bolt Rifle
FAST - Attack Bike: Multi-melta, Twin Boltgun
HEAVY- 5x Devastators: 4x Mulit-melta, Combi Melta/Power Fist
HEAVY- 5x Devastators: 4x Grav Cannon, Storm Bolter/ Power Axe
HEAVY- 5x Devastators: 4x Heavy Bolter, Storm Bolter/ Chainsword
TRANSPORT - Drop Pod: Storm Bolter
TRANSPORT - Razorback: Twin Assault Cannon
TRANSPORT - Razorback: Twin Assault Cannon

AIRWING

FLYER - Stormtalon Gunship: Twin Assault Cannon, Two Lascannons
FLYER - Stormtalon Gunship: Twin Assault Cannon, Two Heavy Bolters
FLYER - Stormtalon Gunship: Twin Assault Cannon, Typhoon Missile Launcher

I don’t know how good this list is, but I’m considering it for my 8th Company list idea. The planes are super efficient by themselves and being able to function as double the wounds remaining should make them a threat for most of the game.
