The one-dimensional things seems like it could make it complicated to measure the resistance. Especially since the bulk material that seems like people are making isn't being laid down in thin films where you might know which direction the conductivity might go. What if there are superconducting grains/domains that abut to each other, but the 1-D paths are then not aligned? Even if you knew that the "domains" were aligned with each other, but didn't know the orientation, it seems like you'd measure a drop-off in resistance, but not to zero at the critical temperature. Maybe?
