Thank you for educating the forum. Do you have a preference on which ProDisc or does it depend on anatomy? I watched one of their reps who sells the product and they were asked if the C worked so well why did they come out with the Vivo and Sk etc. they essentially said they all work the same. Not sure how that’s possible. The SK keel seems more reasonable than the C yet the C is tried and true. Would like your thoughts.
