Main Question or Discussion Point

Does the cooper pairs spins (up and down) cancelling out have anything to do with anything? Is the current spin polarized in a superconductor?

The spins in a cooper pair add to zero so you have a scaler particle that behaves a little like the higgs'. It gives mass to the photon stopping the electromagnetic field from penetrating the material. This is known as the Meissener effect.

I think there are some exotic superconductors with a triplet (parallel spins) instead of singlet pairing.
The properties of the ground state are then richer.
