Hanger Advice Please?

Great stuff you have!
For top tier I recomend that you get an Ancile Lancelot, AKA Ancilot, and put Tarans on it.
There are people that loves Galahad, myself included, but I wouldnt run it in top tiers since jump is better in my opinion, so keep your plasma Griffin and replace the Gala with the Ancilot with Tarans.
I would remove the Aphid Patton and put another Griffin with Orkan/Aphids.
The Zeus Carnage would be a Trident Fury.
This is a pretty standart TT hangar for the current meta, but remember that this will potentially change as the new set of bots come out in the near future.
You could go Galahad for plasma in the place of Griffin, but thats personal preference, I dont perform well with it so I preffer the Griffin, as he can dodge DB's much more easier and consistant than the Gala.
Natasha double Trident/Pins would be good for the moment as you save for Fury if you dont have one.

I would replace the Patton with an Ancile Taran Lance. I would also consider running a Fury Zeus in place of the Carange (optional).

Otherwise I think you're good to go. Both the Zeus vs Trident and dumping the Patton Aphids choices are largely due to all the Ancilots in Top. If you're not seeing lots of them yet you might wait.

Sure, after you flank and kill everyone the beacon is easy to cap.

I would add in an Orkan Aphid Griffin to replace the Aphid Patton. That thing is dying now.

Completely different bots. Both have a place, but in entirely different roles. Thunder is a tight map, close quarters specialist, Zeus competes for the range slot and is strong on open maps. I find the Thunder Carnage more fun to play but a glass cannon- fragile in the current environment in Top. That said some make it work, usually guys who don't worry much about meching out either because of their play style, the other bots they run or their clan mates.

I prefer the Zeus Carnage because its a reliable Griffin killer. Thunder Carnage is either a hit or a miss; if a shield bot comes around the corner, you're screwed but if an unshielded bot comes ariund, then you get free damage most of the times.

What else have you got in back?

You can stay as is, or I'd try an Aphid Taran Griff if you want to make a change- you'll need to upgrade a couple Taran anyway. I wouldn't upgrade the Griff or Aphid any further as you'll be swapping them out.

That could work too if you have the Rhino. If you don't it's a bit expensive, and the nice thing about the Griff is that it starts at level 6. The Rhino starts at L1, and you want to minimize spend on anything you're not going to keep long term. That was my point with the Griff and Aphids. I'd try to decide on your long term hanger, then focus upgrades on that exclusively. If you'll have 2 Griffs then upgrade those two and not more...

In that case... Personal preference, but I would try:
Aphid- Ork Griff / Aphid Taran Griff / Plasma Rhino / Plasma Galahad / Carnage Zeus

You could flip the Aphids from the Griff to the Rhino and run the Griff as a DB. I suspect you're a little light on splash for lower tiers and that would help a bit. Don't run the pinatas on the Rhino, not a great fit unless you run ork s as well.
