Can't go wrong with an Aerial:) Got one sitting waiting to be build (after I've built a few others, because my backlog is tiny, yes it is, those piles are something else!)
LotrR doesn't feel like it has a story for a game in it. It's kind of a closed story if that makes sense. That's the great thing with things like D&D worlds, Warhammer, or just any generally built for gaming world. You can be a hero, but you are not the hero nor the only hero. Books in general don't make great games imho.
