I realize this has probably been discussed a lot on here, so sorry for repeating. I'm sure you all understand since us old folks can't remember much (except a few hundred cube algs).
What do you recommend for first learning 2x2? I prefer to learn something I can get good with. Like I think it's pointless to learn beginner 3x3 because CFOP seems easy enough IMO. So with that in mind?
Also while I'm at it how about 4x4? I've done that a time or two but never for speed.
Just really looking for brief suggestions to look into, so you don't overwhelm my simple mind.
