I do quite like Marklin as well. They run well.

I know the next time I’m in WI, I’ll get Everclear as per your advice. Right now I use the “green” stove fuel but they add 1% acetate (finger nail polish remover?) which makes it less ideal.
I’ve been using alcohol gel lately but today for some reason with the chilly rain, the BTUs was down even though on dry colder days, seems hotter...
