Animal armours (bear, jag etc) are fine with some 6b plates for elec
Crafted armours (zombie, phantom etc) are fine with 6a plates for penetration
Standard armours (shogun, paladin etc) are a little low in penetration but with 6b for elec should be ok
Only real problem is the gremlin as it has no pen and very little elec.
If you just want a bit of protection on each of the attacks (cut, impact, penetration, elec) then 4b would give 10 points with 2 or 3 on each of the attacks.
Just checked that stolen imperium, it should work well. How much dam are those liitle mobs doing?
