I'm a CFOP solver but I've been trying out Roux recently, I average 55 STM (bad I know) mostly because my blocks are pretty bad, but even with slow turning I still get decent times. I think I'll still stick with CFOP though, it's more comfortable for me. It just depends on your own preferences. And using Roux is not wasted potential, some people are just more comfortable or faster with Roux
