The hard decision ones are mission, big z, Canderous, and Carth.
Hk47, bsf, Jolee, bastilla, jkr, and Darth revan all have enough skills that g11 is actually enough, or enough use that it's silly to have not zeta'd them (like Jolee).
Right now My mission is g11 and zeta'd and 18000+ power. My Carth is g11 and zeta'd and 18000+ power once I get the 7th star (87/100).
Canderous is 17350, with g12. I have 2 g12+ pieces I can put on him, either will get me there, but I think I'll just give him a full set of 6 dot mods (his mods are 5 dot purple or gold right now) and he should just sneak into it. Big z is 17430, same boat, either can put on one g12+ piece or 6 dot mods. Although I'm considering his zeta cause the OR team is pretty fun (my g8 juhani is a weak link in it though). I feel bad having to have g12 these two before bsf, hk47, or some of my other teams (like my zEp will probably forever be g11+5)
