Normally I wouldn't even consider fooling with them, but I need some small tanks for Adv. Gas Blending certification, so I'll be pulling them apart this week.
I use 6s when I teach that course.
A. It is very difficult to mix accurately requiring a lot of precison
B. it doesn't waste much helium.
 
3AA 2150. Not so much gas, and probably terrible buoyancy characteristics.
The picture shows 2 tanks ICC3AA 1800 psi and ICC3AA 2150 psi they are steel tanks with excellent buoyancy. I have several double sets.

I’m guessing you need them doubled because they are so small?
