I use the RU one (the first one is different). Solved side at the back. I wanted to find algs that can solve with solved side at the front or minimizing AUF at the end.
R U R' U R' U' R2 U' R' U R' U R - Ua with solved side at front, U2 AUF
R' U' R U' R U R2 U R U' R U' R' - Ub (flip side of above)
Looking for more algs like this. I don't know if there's a mirror of the above 2
