So I've finished with PLL and OLL (technically I have 4 OLL algorithms left that I am really reluctant to learn) and so now I am moving on to ZBLL. I've decided to start with T-ZBLL and all the resources I've found say I should recognize the case by recognizing the COLL case and then look at the position of the UFR edges to identify the case. But I've found it easier to to look at the pattern of the blocks on the U layer (kind of like PLL recognition). Is this a good way to do it? Or should I make a habit out of the first way of doing it?
