Creative thinking is always greatHas anyone thought of Roux-CT? All you would need to do is tsle during second block and a loose subset of ttll for cmll. Since the edge of tsle isn't necessarily oriented and could be in DF or DB, there would be a lot more cases if you wanted to do it in one look. But if you immediately inserted the edge to DF, you could do change the corner orientation without needing to juggle where the edge is. The goal is to get the corner orientation to match a 1 trigger tsle. This should be able to be done with one trigger. Then you insert the edge back into the top layer with an M' or M2 and do one trigger to solve tsle. After writing this I realize that it is essentially making them all a 4 trigger case that alternate between <M,U> and <R,U> but 1. It's pretty intuitive even compared to normal tsle 2. it can be mirrored to the back slot and would only be 48 cases after the edge is taken out and 3. there's lot of tricks you can do to make cases mor efficient eg. you could insert the edge right away to reduce it to a 2 trigger tsle case.
Then ttll is simple you just generate some algs that disregard eo and the M slice but solve the corner permutation. You could also generate a few more that swap DBR with UBL without needing to do an ADF at the beginning and end. The result is raising the skip chance of cmll from 1/162 to 1/30 and making the recognition of cmll easier.
If anyone has a better idea to do tsle during SB let me know.
I think it's not as good as normal roux, because it's the same amount of steps as doing the slot, and then the CMLL.
