Any good tips on how to improve on 2x2 Ortega? I think I'm pretty good at planning and executing the first layer, but my look ahead isn't that great, so there's usually some pause before OLL, and also a slight pause when recognizing the PBL case. I think the last one is my biggest problem. Also, should I bother learning the Y-Perm, A-perm and whateveritis-perm (where one layer should swap horizontally and one diagonally) upside down to reduce cube rotations? I average around 8, most of the time sup-8, but I get a sub-8 average every now and then.
