1.6" will be lighter,but not necessarily faster. Actually,the thinner tire will also be shorter,so you will actually be reducing your gearing a touch.
I've got Supremes in 26x2" on my all-alloy Pt Reyes. I had some 1.5" WTB's but these ride much better. If I had a steel or carbon fork,I'd prolly go narrower.
