If bone augmentations increase your unarmed damage and make it physical damage, what is your unarmed damage with a cyber arm.

Seeing as how the bone density bioware doesn't increse it just switches you from S to P, I'd do the same for cyberlimb strikes.

Sounds like a reasonable way to go.

I might rule that cyberlimbs use the same DV/Type as titanium bone lacing, but that's just me. Aluminum might be the way to go, too.
