With M2, I notice how shooting to UF and FU for instance can both be done with U2 M' U2 M'. When this is targeted at the sticker FU the peices become flipped. So is the best way just to flip the pieces at the end or do some people use different algs to solve the orientation as well. The same thing goes for DB and BD.
Thanks.
The algs Vcuber gave you are good, but with a little more effort, you can reduce cases that include targets in the M slice to much nicer "algs" by taking into account the target directly before or after it. Since it is a good idea to memorize targets in pairs for M2 to keep track of the M slice, this is easily accomplished.
Let s be any sticker not in the M slice. (s) denotes the regular setup move:
FU -> s: M2 (s) M (s)' M
s -> FU: M' (s) M' (s)' M2
BD -> s: M2 (s) M' (s)' M'
s -> BD: M (s) M (s)' M2
For the following two, the setup moves for the UL and UR pieces are switched:
BU -> s: U2 M2 (s) M (s)’ M U2
s -> BU: U2 M’ (s) M’ (s)’ M2 U2
So for example, lets say that my next two targets are FR followed by FU.
Using the tricks above, I would do M' (U R U') M' (U R' U') M2
These are just commutators with a setup move that cancels, but you don't have to understand that to use them.
Hope that made sense. I just use speed optimal commutators for targets in the M slice now, but I learned these tricks from deadalnix and Macky.
