SRO works very well for these textures.
It appears that I completely forgot that I had already installed SRO in accordance with the guide. Unaware, I re-downloaded SRO, had fun learning how to optimize the textures, and when I tried to install it in MO2, I was informed that SRO was already installed. LOL! So I went back and looked at the guide and sure enough, it's in there along with a link to the DDSopt guide.
So, my original post regarding the wood textures was about Real Wood Textures - Farmhouses, an oldrim mod used in the guide. And I now see that due to load order, it replaces the SRO textures. I found Realistic Wood Effect on the SSE Nexus and thought it would be a good replacement for RWT-F especially since it doesn't include the two stonewall files that the guide hides after installing the mod. But, alas, RWE doesn't have a "no moss" version.
In the end, I agree with you that the SRO wood farmhouse textures work well. I ran the game three times to see the textures for all three mods and I like the SRO wood farmhouse textures the most. Subtle differences but once you see them...wow!
