Serius is the best one I've come across.
I vote for a very light balaclava. It allows me to get by with fewer layers on the torso and feels so comfortable in wind. Through most of the winter here (10-35F), I wear a light shell with baselayer and light wool sweater underneath. If I didn't have the balaclava, I'd be looking for another layer.
When it's colder I have a poly scarf/mask, much like Machka's, that really helps with the wind.
I have a heavier balaclava, but find it too hot for just about any weather.
