Something new I like is Thom's CLL + 1 edge, L3E idea. That's interesting
What's the concept of CLL + 1 (didn' find the threat). Sounds like a lot of cases (42 times 8 is maybe to high as an upper bound )
Or is it anbout using MUM' conjugation?
2 opposite 1x2x2 blocks
1x2x3 block in the back or front.
CMLL EO(keeping the D layer edge correctly permuted)
L5E
"2 opposite 1x2x2 blocks" - if I were able to plan ahead this in 15 sec (even with non matching side colors ) in up to 12 moves, I would do it...
roux ending
"EO5 + L5E" - I'm doing this if I get an D edge accidentially soved during an Roux solve, others maybe too?
"1x2x3 block in the back or front" - that I'd hate because it means to refocus on a new color (not R/L color).
Does anyone think it is worth learning L4C for the last step
L3C is much better 23 cases but only 7 essetially differnet ones, also regognition is much easier, movecount much lower, and acceptance for your
methode maybe much higher.
P.S. When doing Placeing your last Slot altering between URU'R' , U²RU²R' (R'FRF') will always ensure at least on oriented corner in last layer, but
you have to try out if that might help you
Question: do You asume center pieces to be solved from the very beginning of the solve
I used to play with a method similar to this,
4 F2L pairs
CLL
Orient edges while placing D edges
U/H/Z perm
I was also trying this (did Center placement after CLL ), but never reached my friedrich times (I'm not even a regular friedrich solver)
