Hi all. I am new here, but not necessarily new to hiking. I've done many weekend trips all across the south and east coast. This time, I am venturing to the Lost Creek Wilderness in Colorado. I'm absolutely excited about hitting the mountains and the opportunity to see the fall colors.

Here's my question... Given that the forecast is calling for temperatures in the 20's at night and we will be between 9,000-12,000 ft... should I take my Jetboil (isobutane), MSR Windpro (isobutane with windscreen and invert-able canister), or my MSR Dragonfly (white gas)? I really want to take the Jetboil, but I am concerned that it will be too cold and the altitude is too high.

Any thoughts? Appreciate ya'lls opinions...
