Snow Peak Gigapower stove windscreen: worth it? what about using a cold canister? is that bad?

Bottom line: do your best to cook in a place that is sheltered from the wind! Snow Peak steel windscreen for the Snow Peak Gigapower stove: is not as good at reducing boil times as a cheapo windscreen, and weights 4 times as much (2oz vs. .5oz) (correction: MSR Titan Kettle is 850ml, not 550ml)
