This is the route I ultimately took and it has worked out well for me. Most of the multi-packs I found had individual rolls that were too short to really be practical. I considered buying two packs, but with a lot of brands there will be some variability between two rolls of the same color which means you can’t switch mid-print. I ultimately found a pack with rolls that were twice the typical length and that has worked out well. The one I bought was Mika 3d brand on Amazon.
