Algorithms for the Last 2 Edges of Big Cubes (Advanced)

Note, I got Y & Z mixed up throughout the tutorial. *

This tutorial teaches you to new algorithms for the last two edges of the 5x5 & 7x7 cubes.
(After learning the ones for the 5x5, there's nothing new to learn on the 6x6. But there is some extra information you need for the 7x7.)

For an advanced method for the rest of the edges, check out Rob's tutorial:

Here are the algorithms used:

R U Ll' U R' U' R
(Flipping Algorithm)

{Uu2 Rr2 (y z) U2} r2 {U2 (z' y') Rr2 Uu2}
(y & z are correct)

(Lll Rr) U2 Lll' U2 Rr' U2 x' U2 Rr' U2 Rr U2 Rr' U2 Rr2

[Ll' U2] [Ll' U2] x U2 Ll' U2 Lll U2 Rr' U2 Ll2

{Ll U2 Ll2 U2 Ll' U2} Ll {U2 Ll' U2 Ll2 U2 Ll}
