The black PVC I got from Home Depot was fine.
My last coil was a 4.5" job made from the solid ABS (not the foam core stuff they have now), and it worked fine. I only mention that it was solid as a reference point, not to comment either way on the foam core type.
My current coil (6") is wound on the thinwall white PVC (ASTM D2729), and it also works fine.
