I guess I don't use CF then... I use an advancement of CF method. I do blockbuilding for the first layer of Waterman...
If you consider that there are pretty much 3 types of methods, (layer by layer, edges first, and corners first) Roux would fit into corners first.
This is a quote from stiff hands' website...
"There are basically 3 different methods of solving the cube that are suitable for use by humans without the use of large lookup tables; corner-first, edges-first and layer-by-layer"
If you consider what's been said here, doesn't Roux sound most like CF?
