I use UF for edge buffer. Was considering UB as well, mainly because I'm used to the R'UR' version of the U-perm that swaps left back and right edges. But in the long run I think it's better to learn the M2 execution of the U-perm as well. With UF as buffer, I realized I get a very useful alg by setting up with M', then doing the R'UR' execution of U-perm, then undo setup. Could do same the other way around with UB as buffer as well, of course.
For corners I'm now using UFR, haven't decided yet if I should stick with this or switch to something else. I do like the insertions from UFR though. For example sledgehammering UFR into the back face feels a lot more natural to me than sledge hammering UBL into the front face. Though I'm sure that difference would eventually disappear with practice. In any case, I think the one move longer sledgehammer execution for those cases is a lot faster than the standard insertion where you first bring the piece out.
Ah, I see. I've been trying to use the ring finger. Maybe pinky works better. At the moment the static friction is so big that it takes a bit of force to get the M slice moving. Not so much that it's a problem with the M' move, but pushing the M move from a slightly awkward position feels a bit heavy. Not sure if this is how it's supposed to be or if it means I should loosen up/lube the cube.
