Absolutely agree with you 2post. Refilling seems to have just become a "thing" recently though. As long as I've thrown out some info for people to consider I've done my part.
Some good visual data on the gases here. Note at 30C (90F) 100% Propane has 5 times the vapour pressure of 100% Butane and the difference increases with higher temperature: https://www.engineeringtoolbox.com/p...ix-d_1043.html
And an interesting video showing a couple types of valve systems: https://www.youtube.com/watch?v=lpJQ5V6PQ4k
I'm gonna leave it at that people, better livin' .
