Just in case you are a bit leery of full cover windscreens over canister stoves, please note that Snow Peak has marketed a windscreen that goes over the burner and supports, but is above the canister and nozzle. Only problem is that it is a little heavy, over 2 oz. So, a Ti pot bottom was used to make a knock-off. Here is a photo of the SP screen on the left, the Ti knock-off on the right:
Here are front and top view photos of the knock-off screen installed:
The Ti knock-off is under one oz. and has seen extensive use with no problems.
As you can see, the Titanium gets darker and discolored when exposed to the heat, but it doesn't effect the function.
Not only does the screen make it easier to use the stove in windy conditions, but it also adds to the life of the canister. I used to get 4 1/2 days from one of the Coleman canisters, and now get at least six, making the one canister safe to last for a week. A day's use for me is a dinner, boiling a liter of water, adding some to a dried food mix and simmering that for 10-15 minutes, then adding some more water and boiling another half liter for tea and washing utensils; then boiling another liter in the AM for tea and hot instant breakfast with gourmet coffee powder. Multiply that by six, and that is what I'm getting from the one canister; so only one is needed now for seven days of trekking.
The more expensive canisters don't last as long, so I don't use them. It may be that the ones with Isobutane might be better for cold weather use. Don't know - have never tested them.
The titanium was cut with a high speed Black & Decker rotor tool using a small diamond coated wheel sold by Dremel as an accessory. Holes were drilled for the center hole, and at each end of each slot. The diamond wheel was then used to cut out between holes to make each slot.
I would not use the stove with the screen in a tent, due to the probability of increased carbon monoxide; but have used it often just outside the tent floor under the tent awning in the rain with no problems to date.
