I'd probably go for either chromium or nicrosil, probably nicrosil for added punch when their tin explodes.
As a ferring the only real option I have is to go for steel and make a grab for the linchpin. None of the other abilities are very helpful....

Inquisitors have extra iron/steel, which is the only way they can see metals in the body. Otherwise, the investment in it would block out the metal signals.
Ergo, if you stored investure and then tapped it while fighting an inquisitor......you'd be invisible to it. Granted, they could try to listen with tin, but now they can't see you and will likely be wierded out at not being able to. I love it.
Twinborn nicroburst and soulbearer. All the way.
