I'm not too familiar with the Jet Boil, but one reason I'm big on titanium is because it has a melting point over 3000°F.
...the flux ring on the titanium version of the JetBoil Sol is aluminum...
If the Titanium JetBoil Sol has aluminum where it should be titanium or stainless steel there is definitely a problem. Should the flux ring be something other than aluminum?
Better is the Enemy of Good Enough.
Okay, what’s your point??
