I think we're in agreement. I see many generations of space colony
before we get to large cylinders, and I've outlined some in he

(this is not my most up to date thinking)

However, I don't really see the merit of your next design. A 100m
inflatable hull would either be very thin, and hence no meteor /
radiation protection, or very heavy. My HEO2 station has habs rotating
in free space, and then covered in NEO material for protection. Given
a low gravity environment, and enough tension cables, this should be
quite feasible. [It has been pointed out that a three hab structure
would be more stable than a 2 hab structure]

I've also realised that if Rotovators work, LEO will serve virtually
no purpose. High Earth Orit will become easier to reach than Low Earth
Orbit.
