after approximately 50minuets burning time (with pot on top and filled half way up), the canister temp seemed to be within reasonably temp. range. I did like Bluefishe's approach to a screen/shield. and will try to elevate the shield about 1-3" above the surface that the stove's canister sits. allowing a bit of fresh air to bleed under and cool the tank farther. at the same time focusing the heat onto the pot, were it's wanted. So with that in mind I'll be testing it on my upcoming hike, tentatively planed for after the 4th....thanks to all who replied
