I'd look at the Wiki for a list of runes and insignias. Sig's armor is all decked out at this point (at least, as decked as Pre armor gets :/ ) with Survivor, Radiant, Vitae, and of Attunement, with a Knight's on the shield. This is optimal for a w/mo in my situation (trying for LDoA) because it gives me enough hit points and energy to live solo against all but the worst combo of Charr that can exist in a Northlands patrol. Look at the possibilities; unless you HAVE to have those higher skill bonus runes I'd think about skipping them, the +1 runes are still a noticeable benefit without the hefty penalty.
