I spoke to a mountain guide about Eiger west flank in a pub last year, he said it is easy, and that he had climbed it without crampons. Here are two views of the gradient, it is not extreme at all, people ski down the west flank. The weather, is the main risk.

The North Face of the Eiger has a gripping history, there are many very entertaining documentaries about it, this is one of the best: http://www.dailymotion.com/video/x3ntsiw
