Imperial troopers

In farming the troopers at the moment (veers, starck, piett, range, gideon, deathtrooper and snowtrooper. Now I have quite a good team. But I don't really know how far I should take them.
I don't have the resources to relic everyone of them, so which troopers should I relic, which should I take to G12 and which are ok to leave at G11?

I'm not planning on going for SEE in the near future, so that's no argument for me at the moment
