The problem is that energy resistance costs a lot more than the SR (more than twice as much!) if we're counting gp. Rather than blinding, let's go with +1 animated for the shield. For the armor, we could go +1 (your favorite energy here) resistance if the price is right.
You know, this pricing has always bothered me. By the time you can afford some of these properties (like SR 13), it's mostly useless.
