I wouldn't want to travel with TF-4 because it seems to have been designed to be completely mixed (as opposed to being a concentrate you can dilute as needed), although I suppose you could mix it into batches of stock and travel with those. Seems like a pain to me. TF-4 is an alkaline fixer by the way. TF-5 is a totally different formula and is close to neutral in pH.

Even if you use a standard acidic fixer you can skip washaid/hypo clearing anyway with film since the wash time is not all that long to begin with. One less chemical to travel with.
