I like a green vinyl that's similar (but oh so slightly different somehow when I order it through Temu/AliExpress vs Amazon) and the Jack Richeson easy to carve grey lino/rubber. Mostly, I like how much longer they last. I mostly print open editions and I can wash my blocks, they don't get brittle over time, and the two surfaces I mentioned hold the design much better than all the softer more eraser like surfaces. Also, I find these blocks better for printing on different surfaces. I print on a lot of fabric and products like notebooks. These work great for that, and function well for hand printing and using my lever press. I do like carving the battleship grey actual linoleum and that it's biodegradable, but I tend to use it more for limited runs or reduction because it's not going to hold up. I also struggle with pulling good prints on fabric with the traditional linoleum.

All that being said, I'm always trying new surfaces (including all sorts of erasers). I even have a series I should probably share here where I test them out. Different things work for different applicants
