The bryan disc has a high level of auto-fusion occurrences from what I've read. The device also looks weak and I've read of debris from it as well (the outer sheath ripped). That being said, overall the results were decent enough for FDA approval. Though I don't like ball and socket, I would weigh that disc against the prodisc if I were you.
