Tag-Team Farming?

So there are alot of threads out and about about clocking speeds and efficiencies of different single (or pocket kin'd) farmers out there: elec/shield scrappers, arch/mm blasters, SS/Shield brutes, but what do you guys think would be the best pair for farming? Would it be Fire/Kin controller with a Granite tank? Two SS/Shield brutes taking a mob each? This is just all for fun and theory, so let's assume any combination (reds and blues can cooperate in RWZ), and assume the two are friends so they can reasonably divvy up the rewards and such.

Elec/Shield Scrapper and Kinetics/archery defender. With speed boost and fulcrum shift the scrapper should be able to LR + SC every mob in pretty much one shot. Then, the defender has RoA to mop any reaining baddies.

My old testing used Herostats to compare #s. Fire/Kin Controllers, various SS/X Brutes and Fire/Psy Dominators were all roughly close. A Fire/Kin Corruptor + an SS/Brute working together were significantly more efficient than two of any of the first set going in two different directions.

To give the general idea (these #s are not accurate):
100,000 Inf per minute = Fire/Kins, SS/X Brutes or Fire/Psys fighting their ideal enemy under ideal conditions, repeatable and sustainable.
200,000 Inf per minute = Two of any of those working separately and in different directions would combine to gain 200,00 Inf per minute (really, you'd have to adjust for teamsize etc. but I did all that in my testing).
300,000 Inf per minute = Brute + Kin working together... adjusted for teamsize etc.

I did not test any other duo combinations or other toons working together. I would be willing to help people use herostats to gather new and accurate data in a standardized format to compare various strategies.

What's being farmed? Are we talking AE or something likethat (Where numbers can be a little higher ) Or is there something else that is generally being used as far as numbers go.

The numbers I recorded generally represented the ability to level a teammate quickly. I generally let anything go and let players load whatever mission they wanted against any foe they wanted. I did not focus on items nor try to calculate how one could play to make the most money. My #s were not entirely accurate on the subject of leveling teammates because Boss, Minions and Lts give different Inf values. However, it was clear that those 3 common farmers were very close and clear that the Cor + Brute pair was some margin more effective.

I was generally thinking about speed, so I wasn't too worried about what was being farmed. I assumed that the farming pair would have already figured out what they'd be best at fighting and would fight exactly that.

Since Bosses, LTs, and minions are supposedly scaled in risk vs. reward, I figured the best measure would be inf/min, since different maps sizes and mob types would effect any other measure.

...DaveMeb's choice seems pretty logical: my guess would have been something like a earth/emp controller coupled with a arch/fire blaster. AB + RoF = death

After GR, I'd bet a Fire/Kin troller and a SS/FA Brute.
