I know this has been discussed in the past but I want to bring it up again. Since I now have two steam locos with smoke units I'm curious about what brands others have had the best luck with. Mainly quantity of smoke. I don't care about "home brews",just the commercial brands. I have tried Aristo,USA and JT's Mega Steam. I think by just a little the Aristo brand produces the most. I love the smell of the JT oil scented. Any input?
