Ok, I've been using my windscreen for years. Used it with my alcohol stove, used it with my MSR Pocket Rocket, and likely many other stoves. I have heard that it is not advisable, say even dangerous to use with canister stoves. I'd like to know something definitive before I blow up myself & my hiking partners. My particular screen is just a home made model of medium gage aluminum, which folds up nicely. It seems to work, and I just thought I'd ask for an opinion.....
