Thanks for the heads up on the sale!!! I just went to REI and blew $300.00 bucks but hey I got some pretty cool stuff at least!! I did pick up a jetboil also, I am itching to try it out now.

I use Jetboil quite a bit, one thing that I found out (probably very obvious to others), but once the water boiled, do not take it off the can to pour it. For the last year when I went with my friend's Jetboil, we kept taking it off the gas can to pour the water, then mount it back on and heat up more water. How idiotic is that? Then one day, on a river trip, I just picked it up and poured water out. It was too simplistic to realize originally LOL anyways, as stupid as that sounds, just wanted to pass it along.

So its no secret that MSR came out with a copy cat that works better than the Jetboil.

My big question is how did the Reactor perform in temperatures below 20 degrees?
In the store dude freezes a canister in a block of ice then fires it right up on a reactor stove. The illusion with this is the coldest the block of ice will ever get is 32 degrees. The ice acted like an insulator.
Any one ever use a reactor in colder temps? At elevation?

None of the info I've seen yet answers the sub 20 degree question.

Ice can be colder than 32 degrees.

Also, correct me if i'm wrong, but the issue that makes jetboils perform poorly in cold weather is the gas canister, and the fuel blend in it. The colder the canister, the less pressure there is, and gas isn't vaporized as easily when it is propelled through the jet. So, you'd think the two stoves would perform similarly in equal environments. I seem to recall something saying that the msr blend works better though than jetboil blend of fuel, because of the ratio or isobutane to propane.

I guess I could be incorrect though. Just assuming.

True story.
Rasberry farmers for years have soaked their fields with water on the first night the freeze occurs to coat the vines with ice. This protects them from sub freezing temps later on in the winter.

Also as the temps drop the pressure in the canister decreases also. HOWEVER the MSR Reactor has a special pressure regulator inside that is suppose to ajdust the pressure, though I can see how (mechanicly that is.)That way the burner has a steady flow.

My main question is How's to work in colder temps? Does this pressure regulator realy make that much differance?

I'm heading uo Touchstone wall in Zion on Saturday. I'm stoked!!
