using second razor with what weapons to equip

Im building up another razor wing so I'll have two on the table, I was thinking one for anti infantry and one for anti tank. So one with necrotoxin missiles and and disintergrator cannons and one with dark lances and shatterfield missiles. S7 however isn't really tank busting so should I just keep them both for anti infantry?
Thanks

Stick with the lances, you will wish you had more than once! If you want more AI just add the nose cannon. I prefer stock missiles rather than paying to upgrade them.

I also keep them the same otherwise you will invariably with you had the other load out when faced with a potential target...

I dont see the point in upgrading on the Razor, but the shatterfield seems to fit the voidraven best

Yeah but its odd that the missiles are all AI and the dark lances are AT so putting them on the same war machine cancels each other out as you of course have to shoot all your weapons at the same target. I guess at least with giving it two disintergrator cannons makes it all AI but DE have an abundance of AI weapons as it is. I have an opponent that plays space wolves and his whole army is merchandised, a whole line of tanks and a couple of whirlwinds at the back that really annoy me. Wish we had some S9 or 10 weapons.

I'm allying with Eldar to get Eldrad and some other nice eldar firepower and they're battle bros too but their high strength AT weapons are a bit thin on the ground as well.

I'd keep the lances on the razorwing. Gives it a shot in a dogfight. If you keep it stock (and give it a flickerfield, so you can get the 5+ save without having to forfeit missile fire) then you can send if after high-armour targets/tanks with the lances, or infantry/very light vehicles with the missiles. Its one of the few units with a decent amount of duality to it as it can switch between anti-infantry and anti-armour quite easily

My opinion changes a lot, but lances and monoscythes on Razors, and Lances and shatterfields on Voids is my view again now.

The missiles are going to do far more infantry killing than dizzies, so I'd stick with lances.

How do lances kill infantry better than dissies?
If you want lances I'd say use the void raven

Yeah I didnt realize void lances were S9, that's a tank buster, so Void raven bomber, will have two void lances on each wing, the void mine, can it use that only once? but what missiles will I give it? they are all pretty much AI.

The other fighter I'll make a razor wing with disintegrator cannons and necrotoxin missiles, wicked AI
Glad I pained them different colours to tell them apart.

i'd vote for Dissie/SC for anti-infantry purpose, splinterfire is good but sometimes you will need something [s]special[/s]

And drop missiles, stock ones already wound most of infantry on 2's
