I think Bone Claws Wolverine would do a lot better than people give him credit for. Without adamantium Wolverine is way faster, way more agile as he does not have to carry around 100 pounds of metal. His healing factor can repair his entire body being crushed in about 2 seconds flat. Adamantium Wolverine can cut through his bones, but Bone Wolverine's bones are going to mend right after they get cut anyway. I think bones would be able to pull out a victory at least half the time. The other half he gets decapitated.
