Y-Perms are generally the alg used for corners in OP.
There is no real consensus as to whether you should solve edges or corners first when you’re first starting out. Just do what is more comfortable or what makes sense. I would recommend to memorize in the opposite order of what you solve. So...
If you are really having trouble with M2, OP is not a terrible way to go. Since you already know OP for corners, edges wouldn’t be too hard. After getting a few successes with OP you’d understand BLD better and be more motivated to learn M2.
Ohhhhh. That seems like it would not be worth the time save. You wouldn’t have to do an extra alg but I already get confused on occasion doing the swap on 3x3, that would be a nightmare with wings.
Solving them swapped is a great way to do it, but you have to memo corners first to know if you have parity, and it can be difficult to implement. But it is definitely worth it. Give it a shot!
I recently did a 25 cube multibld using only non-magnetic Little Magics, and none of the DNFs were due to execution. If you tension them right and dot turn too aggressively you shouldn’t have a big problem.
Yeah, I do that occasionally with my index finger. Middle finger would work fine
That piece is BU, since the sticker is on the back, and the piece is also on the up face.
