Good. The earlier, the better. I see using CFOP as a bad habit for me, and I now can't stop using it I would recommended trying to start the good habits (i.e. being y-axis neutral) early on too, but I think you should get more comfortable with EO before trying that. After you're reasonably confident with EO, try to learn y-axis neutrality, but for now don't worry about it. You have enough to do alreadyI'm definately going to do some slow solves to see if I do it in a fix routine or not, thanks for the warning
Hopefully I can eliminate the bad habits early on.
