the best thing about this is only 2 really fast oll cases and f2l can go at about the same speed as CFOP. the thing is tho I only just came up with this today when I tried to learn roux took a break and intuitively did some moves from CFOP and BAM the cube is solved
This is a slower version of a method called ZBRoux. in ZBRoux, you do those first two blocks, then finish the first 2 layers while solving the orientation of all the edges, then ZBLL.
