I was using rolls. When I first started colour I got some Kodak Edge rolls really cheap and I practised printing on those. As soon as I was confident I moved onto Endura sheets and when my stocks run out in a few months I'll start buying Fuji which is being cut down by a 3rd party here in the UK. As to the question, how did I cope: I didn't! It was awful. My darkroom is tiny, tiny, and I had less than an inch to manoeuvre whenever I needed to cut down some stocks. The roll is heavy, I used to place it over my arm, pull out an arm's length and then feed it into a guillotine wedged up against the wall. I struggled to cut the paper straight and normally ended up with paper shaped like a rhombus. If rolls are the only option in the future, I'd hire a large darkroom and cut down the lot in one session.
