3BLD reconstruction of edges.
I use t perm for edges to switch UL and UR
to deal with flipped edges I do R U R' U' M' U R U' Rw' y M2 U' M U2 M' U' M2 y' to flip UF and UB
Scramble: F2 R B2 R' F2 D2 R' D2 R D2 U2 L2 B D2 R' F2 D' U F2 L B2
y' (I like starting with orange front and white top)...
When you hit the buffer you end the cycle, and I usually rotate to get a different piece in the buffer position, however this may not be totally accurate as I have not gotten a successful bld solve
So when you guys get to last six edges do you
(1) do wide foxy
(2) do cll parity
(3) switch to a triangular core
(4) use the er method, as explained previously
(5) just dnf
