ok thanks. but im not sure if this new question is off topic or not, because its regarding the A perm. when you have no sides with two of the same colour (after OLL) do you use A perm two times or E perm? because im still using a little bit of beginner method, and RobH0621 says to use A perm twice but badmephisto says to use E perm.
It solves both ways, so do whichever way you're comfortable with. I started off with learning the A perm and can do it relatively fast, while I haven't practiced E at all and it takes ages to execute. Practice is all it takes.
And I suggest learning a few of the no-headlights PLL's like Y and V once you've got the initial 2-look algorithms memo'd. Don't try the N-perms too early though since they'll come up very rarely.
