1. I'm pretty sure that requires more algs than normal Roux (or at least the "variation" PandaCuber mentioned).you do f2b then cmll or 2 look cmll (2 Algs) finish f2l and finally ether ell or ell and epll.
2. It's slower than Roux. Roux + CFOP is a really slow combination. From what I understand, one of the benefits of solving F2B instead of F2L is that LSE +CMLL can mostly be executed faster than OLL+PLL/CLL+ELL.
