Hmm, that can work. But is "Personal Shields" the skill used to perform these checks? And would this skill count for physical shields, too?
Also, I can see an additional bit of potential rulage for this skill. While Dodge negates Damage all together and has the disadvantage of not allowing another action that round (if done as a reaction in combat, and not declaring additional actions beforehand) like attacking back (counterattack?), or reducing consecutive actions that round by -1D or more (depending on how many actions that character takes), the Personal Shields skill could be exempt from this if using an off-hand and using a light weapon in the character's main hand (knife, sword, pistol, etc). If you make the check, you get the shield set in place and receive the bonus to resist damage, while being able to attack back with the their other hand (which you can't do with Dodge, right?). And if you don't make the check, you don't get the bonus, but can still attack back if you're still standing after being hit.
It comes down to what the character desires more, no damage but no counterattack, or better damage resistance to soak it while being able to counterattack. Options. I like that.
