Starwars clone army, what to use? There are plent of reasons to chose spacemarine, sobs, or ig. Choose the one that you would like to play, should be your first consideration. I like sobs, so my two cents would be for them. Although the huge numbers of clones suggests IG. You could look at one of the special IG armies. Try an all IG stormtrooper army, or elysian drop trooper army. Of course, the most pyshic army in 40k is the eldar. A craft world eldar Ulwthe, may be what your looking for. Guardians to be clones, warlocks to be jedi.
First try some of the armies or at least read about them. Next look at the miniatures you will use. And then decide which is your army.
Food for thought...
Tastes like eldar cheese.
