ZBLL forces LL skips
WV/SV solves corners, which basically means OLL skip if you also orient the edges beforehand
edit:
tutorial for ZBLL is:
1. learn COLL to understand how the corners should go
2. from there, learn to detect edge stickers to understand how the edges should go
well that's actually more of a tutorial for recognition, but yeah, also not entirely sure if there's more for it, i do know ZZLL recognition is basically normal COLL stickers + UF edge sticker
