This is the tape I use. 3M green fine line.
BTW, keep the cardboard backing that comes with the tape. You really want to keep your tape clean. I try (I'm a bad boy sometimes) to always lay it back on the cardboard after I am done. If you lay your tape on your workbench, it can pick up little pieces of gunk on the side of the tape that can stay stuck to the tape and will make a raged edge.
