A sandtrooper may be nice, because if you happen to slip with the knife or something it may just add to the battle damage/weathering? But there are more pieces to put together as you have to get the backpack too. If you are a larger guy the fx might be the way to go, or so they say. If you find an FX lite kit, as in just the armor (no helmet), you can just get a more accurate bucket. If im not mistaken there are some descriptions of the armors as well as the helmets on the starwarshelmets.com site. Might want to take a look over there. But im just rambling, i just have a helmet so im not the most experienced one to take advice from, there are real experts on this board, and im sure someone will chime in! Good luck!
