I'm not sure if this is the right place for this post since I don't need help with lookahead so feel free to move.
I was wondering, with fingertricks being optimized and available to everyone, most of the better OLLs & PLLs easily found on Youtube, Macky's site to optimized intuitive F2L. Is lookahead the last frontier to lower times? It seems like the fastest cubers have no pauses which means they must clear vision of the patterns that are going on at high speed(Faz said something like that in NY Times this week)plus it's the one thing(Other than 'turbotracking)that you can't learn directly from Youtube. What do you guys think?
