I'm thinking specifically of a balrog here. The base is 65mm, the wingspan is 260mm. In a restricted space, like tunnels of Moria, I'm assuming he can move down any tunnel with a width of =/>65mm. Do I need to take any account of the actual size of the model (apart from the practicality of fitting him into the scenery)? Similarly, the bridge I built was 40mm across, wide enough for one figure at a time. This must mean that the balrog can't actually stand on the bridge, so the hobbits can stand at the other end making rude noises and he can't do a thing about it

. Am I correct?
