Remember that CSP makes the alg count go up to about 200 to about 400 no matter what you use. Not that this changes this argument, but if you don't want parity, you would have to learn a lot of algs anyway.I’m not saying you know PBL and I’m also not saying that you have to know PBL to be good. All I’m saying is that Lin needs very few algs to get good at. And while CO and EO recog take less than 1 second, Lin algs can be nearly instantaneous because you don’t have to look at the bottom. And of course EPLL is also quite easy.
