Do I need to learn all the OLLs for sub-20? I'm trying to improve my cross but nothing seems to work.My PLL execution is pretty slow too.(up to 6 seconds) Any links for tutorials on Advanced Cross and PLL execution?
And- is it necessary to be dual / full colour neutral? Because it doesn't seem to be worth doing,seeing as only one or two moves are saved being colour neutral/ dual colour.
You don't really need to learn all 57 OLLs for sub-20 but maybe some of the easier cases can be helpful and easy to learn gradually. I started that way and ended up learning all the cases but in fact some cases are not much better than the 2L option. I mean, we are talking about maybe 1 second improvement at most, depending on your TPS.
For advanced cross look up badmephisto advanced cross on google. He has some nice video tutorials that helped me a lot. For PLL execution try to search for videos on how the top guys execute them and try to pay attention at the fingertricks they use and apply them to your algs. Other than that it's just a question of drilling your algs over and over.
And, regarding CN it's not just that, in average the difference is not big. It's that, having 6 options instead of 1 you have a lot more chances to have a good cross, maybe even an x-cross or at least a cross + easy 1st pair. And, in my case, when the solve starts well it usually ends with a good time. I'm only dual CN right now (white/yellow) but I'm trying to become full CN (my times with the other 4 colours is now like 4-5 seconds slower). Is it worth it? I think it's relative. It will help your averages a bit but probably not your PB single. Anyway, it's something that does not take a lot of effort and will help you get used to it for other events were being fully CN is a must, like 2x2 or skewb. I, for some reason, tried to be full CN but ended up favoring white / yellow and, when I realized it, I was way slower with the others so I stopped even trying, but I'm going for it again right now. I think it's never too late but it's easier if you go for it sooner rather than later.
