I like the pink blocks best. They don’t crumble like the blue ones and the white ones. So far I haven’t liked the Lino or wood because it’s much harder to carve and I can get as much detail with the pink as I need.
I tried tracing with carbon paper and all that but now I just keep it simple by free hand drawing with a ballpoint pen. You don’t have to follow the lines exactly and you can really see what you’ve got with no smudges.
I use a bunch of carving tools that you can buy in almost any art supply store. “NIji” brand tools have a straight wooden handle. “Speedball” has a set with a bulbous red handle. I don’t recommend one over the other, I just pick up whatever feels sharpest and right at the moment.
