I am practicing my F2L lookahead right now and right now, I kind of follow a corner and edge when I am putting another one in and most of the time, I don't need to pause to find it again, but it still doesn't work 100% of the time, do you have any tips? I also tried doing it at 40 bpm using a metronome like Chris Hardwick suggested in some thread I found a while back but it feels really slow doing it that way. I was also wanting to learn some F2L algorithms, I average almost 40s right now, should I bother at this level or just keep practicing lookahead? If I should, what algorithms should I learn?
