Some images to show the DSS texture that is exactly the same as DSA. Nothing new or different about colors or legends. The profile is the only difference
Left is DSA, right is DSS. The texture appears rougher in this photo than it feels. It feels “dry” but it isn’t rough like sandpaper or anything. If you like DSA, you’ll probably like DSS.
Also, I think he misspoke when he said each row has a negative slope. The top two rows are flat.
