Simple question, hopefully a simple answer: what are the benefits of integrity enhancements in a cyberlimb? Thanks!

They make it harder to damage the 'ware. They're for stress tests.

They add body dice when that limb takes damage from a called shot. So if i put one in my cyberskull, my brain is that much more bulletproof.

Of course, since dermal armor/sheath is not compatable with cyberlimbs, you could look at it as a kind of 'armor' for the cyberlimbs.
