I have a Caldera Cone ti Sidewinder stove with alky, ESBIT and wood burning capabilities.
>The ESBIT setup is much more efficient than my previous Vargo Triad ESBIT burner and foil windscreen. Almost 2X as efficient.
>The INFERNO wood burning insert is HOTTT! A true gassifier wood stove like the BushBuddy but collapsable and lighter.
> I don't use alky but the included alky stove is very efficient and Trail Designs has invested a lot of time perfecting it to work efficiently at all altitudes.
The Inferno insert is an extra cost option but it's great for winter camping. Only tinder & ESBIT to carry for fire starters. The wood fuel is lying all about if you're in a forested area. Set the Sidewider/Inferno on some thick sticks in compacted snow and it won't melt down. But be sure to use the ti bottom sheet over the base sticks.
