RE: Head Light??
Both Petzel and Prinston Tec make good headlamps. I do a lot of hiking at night and I primarly use a prinston tec solo lamp. It's light and with the incadesent bulb it isn't bad on batteries. I can get about 6 hours from 2aa batteries. If you ise the halogen bulb it will easily cut battery life in half. You'll get more light but it isn't necessary.
