I don’t get the Low level Fabled Tortoise… Does Krieg have a -shield COM that i’m not aware of ?
strip shield, run fast. minimal max health decrease. easy to strip with one enemy bullet.
No, but if it’s low level, there will be close to none health penalty. Also small capacity means it gets depleted quicker so you can fly around straight away.
Wow, I literally put that that as you did at the same time 
krieg players think alike. 
I see, not too bad.
But I think I’d rather have extra health 
I also thought of the impaler. It’s a bit of a stretch but corrosive DoT is pretty long and it could help keep me burning…
not a bad idea.
Surely, the Love Thumper should get a bit of a shout here?
Or did I miss an exclusion to that?
No, but I guess you missed the “Hellborn no melee” part 
OOPS. Yes, I did.
Read it on my phone then responded on PC. That is a formula for disaster.
A lot of the good stuff has been covered.
You can use the Big Boom Blaster so some effect.
If you use Hellborn, every tick of flames may cause the shield to drop a booster. Meaning that when behind cover, you can literally peak out. Pop em a few times, and go back in to your shell. You can even use it to Replenish grenade Ammo/Rocket Ammo.
… I really should make a build out of this…
Shouldn’t I?
Yeah, you should.
I am doing something of the sort and the BBB is a GREAT idea 
Topneaa spamming is cool on Sal, I see no reason it wouldn’t be on Krieg too 
I’m gonna go kill Pete a few times.
For the Rough Rider vs Neogenator vs Evolution I found an old script I had for max health and shield calculation that I used a while ago at the old forums, these are the numbers I’ve got from a lvl72 Psycho with 5/5 in Feed the Meat, +62% health relic, no BAR and only 5/5 in Numbed Nerves for damage reduction (outside of Rough Rider’s mod).
ps.: Don’t remember if I actually tested these values so uhh, yeah…
No shield
max health: 1124796.0401
health + shield: 1124796.0401
maximum hitpoints: 1687194.0601
depleted shield: 1687194.0601
Rough Rider
max health: 3191028.6001
health + shield: 3191028.6001
maximum hitpoints: 5424748.6201
depleted shield: 5424748.6201
Evolution
max health: 3334558.9601
health + shield: 4129192.9601
maximum hitpoints: 6193789.4401
depleted shield: 5001838.4401
Neogenator
max health: 3334558.9601
health + shield: 3854549.9601
maximum hitpoints: 5781824.9401
depleted shield: 5001838.4401
-?
max health = (base_hp + shield_hp) * (1 + bonuses_hp), where bonuses_hp is the sum of the health relic’s mod, Feed the Meat and BAR (wich was zero for this)
health + shield = max health + shield capacity
maximum hitpoints = (health + shield) * (1 + total damage resistance), as in, the necessary ammount of damage needed to bring both health and shield down to zero taking into account damage resistance
depleted shields = (max health) * (1 + total damage resistance), same as above except for zero shield capacity
tl;dr: Depending on how often your shields are up an Evolution or Neogenator gives more survivability than a Rough Rider, with shields down however Rough Rider still seems better.
What about an Antagonist? It would be a great shield if it reflected bullets and spit out slag balls while it was down.
The issue is how unfriendly both mania and hellborn are with any shield that doesn’t give bonuses whilst depleted.
I know, but I swear I’ve seen slag balls coming out of it while playing Maya and it was depleted. I’ll have to test it to make sure.
Maybe Inertia was up at the time.
That would be my guess too
How about a high capacity / long delay Blockade? If you’re on fire, you’re used to long delays anyway (especially if you start down Mania tree too). Good shield capacity for after FFYL. I’ve read several places that it has a 38% Damage Resistance regardless of charge (even active when shield is depleted).
Back of the envelope math looks like it would have half the survivability as a RR once depleted. However, the capacity of the shield would let you enter fights with more survivability than a RR.
Using the formulas from @Maveco:
Blockade
Max Health: 1,124,796
Health + Shield: 3,641,083
Maximum hitpoints: 6,845,236
Depleted Shield: 2,114,616
So yeah… ignore what I proposed. It’s only +10.52% stronger than Evolution when charged, and -57.72% weaker when depleted. lol.
Given how unlikely you are to keep shields up while constantly igniting I don’t see anything particularly great other than the big boom blaster, roid or +health% shields, even if using an Inflamable-prefixed shield the self-ignition might not inflict damage (or it does 1 point of damage, maybe less… I don’t remember) but it still interrupts recharge.
