My favorite all around windscreen is oven liner. It's thicker than foil, thinner and lighter than flashing. It's also cheap. Titanium is OK, but so light it can blow away. and you are usually stuck with a straight cylinder. With oven liner, you can make a cone - better for shedding wind. An oven liner wind screen 4 inches high and 12 long will weigh about 0.2 oz.
