I'd say don't go with Fellowship of the Ring only. It has very limited fellowship options, while Two Towers offer a lot more on its own. Thinking of available decks to build from sets:
Fellowship of the Ring - rainbow fellowships, sauron grind, nazgul, moria and beatdown uruk... great shadows btw.
Two Towers - rohan, rangers, elves, hobbits with treebeard, uruk site control, uruk tracker, uruk archery, southron archery, easterlings, dunland.
Also, you can't go wrong buying reflections.
