Thank you GrantSP, That really clarifies my general thinking. I believe that the mods I want to remove are mostly texture mods. There are several though that I am not sure about. Beautiful Whiterun, Better Jorvaskar. Caribou Gone, Detailed Terrain and Tree LOD, Enhanced Lights and FX, Much Ado Snow Elves. I want to try some scripted mods and some ENB next. If there have been script additions / changes via mods, then it seems like the safest course for the current game is to just install new mods checking for load order and conflicts in advance, and letting the new mods overwrite what they will???
