The only time I don't use MF is if I'm hiking more than 15 miles, or if the emulsion I want to use isn't available in 120/220.

One of these days I'll learn how to use my 4x5 monorail and use that for stuff that doesn't move and within 100m of a car Or if I get a pack mule to carry all of it lol. But again, there is even a bigger emulsion problem there...
