You're welcome.
A Helios will work in colder temperatures than a Jetboil almost irrespective of the brand of gas, but if you're staying above maybe 20F, then a JB with good fuel should be fine. There won't be that much practical difference between 85/15 Snow Peak and 80/20 MSR. BUT do avoid Primus, Coleman, etc. that have "plain" butane in them.
