I started using Quilter Select. They too have a soft sand paper like finish to the back of the ruler with fine lines and and small dots for diagonal cuts. They are easy to line up and nothing in the visual lines to interfere. I just love them. Sounds like this ruler system is the same or close to it. The no slip factor is a big one. These rulers are a bit pricey but I am finding them worth the money. Thinking about asking Santa for a couple others for Christmas.
