I've started using this now, too. So far I've always done AUF first to
solve two corners (usually ULF and ULB), then with a second look
recognize the PLL fully. Now I've drawn pictures of all the PLLs and
their blocks and from some first experiences with it I must say I like
it a lot.

One question, though: Do you really define blocks that strictly? For
example, consider case n3 and n9. According to your definition,
they're equivalent. Both only have a triple-block of a corner and its
two adjacent edges. But n3 has another "non-adjacent block", two
corners which share the same color on one side but the edge between
them has a different color. But they're still easy to identify as a
"non-adjacent block". Do you use this or do you differentiate them a
different way?

I think I've heard of the block-approach before, but never thought
about it much. What recognition methods do the other top (PLL) cubers
use?

And a question for top F2L cross on bottom cubers: When you for
example do (R U' R' U R U' R'), do you prefer using right thumb to
push or using left index finger to pull the U'? I noticed I've been
using the thumb but the index finger seems to do a much better job.
