By now these are the last mastermorphix ELL cases for which I have not found an algorithm. They are mirrors and inverses of 2 cases; on algdb, these are listed as 1) LF-flip Ub and RF-flip Ua; 2) BL-flip Ub and BR-flip Ua. I do believe these are very much solvable rRUF, but cubeexplorer lacks wide turn options altogether.
