I started out as a film assistant, and while I enjoyed doing it while it lasted, there’s no reason I would ever go back and actually edit film. If I were so inclined, I’d cut on an Avid, and maybe go make a work print for the hell of it. (Depending on length, etc.) Cost would very much be an issue when renting all the stuff you need, and it actually takes a little skill to make a clean splice, sync sound, and use a flatbed.
