Sub for M2/OP for me usually required sub 1:05 memo. Try turning faster too.

What's the best method(s) to upgrade to after learning Old Pochmann for edges and corners?
Riley

Definitely M2 edges. It has easy set ups, quick switching algorithms (M2) and is very easy to learn after OP. After that, I can't help you, because M2/OP is all I know.

how does one speed up execution using M2/OP?
i memo roughly ~1min now but still get sup 2 30

What algs do you use for OP corners? If you are only using the Y perm, that could hurt a little due to extra setup moves. I use Y and both J's and it saves a move or two here and there.

Zane has a M2 video that suggests you use setups to the buffer to lower movecount(more effiecent conjugates)
For example, with a DF buffer, shoot to LB,DR,UR,FL
First setup LB to UB with a B' (instead of L'BLB'),then M2 Shoot to DR with UR2U' M2. Undo the setup with a B. (B' M2 UR2U' M2 UR2U' B)
then UR, FL would be (U' M2 U'L'U M2 U'LU U)
An even better improvement wold be seeing the easy setups to M'U2MU2, so Shooting to UR,FL could be done as (L'U' M'U2MU' L)

I use M2 edges and OP corners.
What do I do when I shoot to BU and the M slice in in "parity" position?
I've run into this situation a couple of times and I'm not sure the best way to deal with it. As far as I know, when you're on the second letter in your pair. the M slice is off by M2 which means you shoot to the opposing slot, which would be the buffer position. Am I suppose to deal with this in memo, or shoot somewhere else and fix it after?

You only have to think about this "shooting to the opposite slot"-think, if you want to shoot to UF, FU, BD or DB. If you have to shoot to BU, you can use your normal alg. It doesn't matter if the M-slice is off or not.

In 3x3BLD, how do you solve when you have a couple of 2-cycles, edges or corners, to solve? They could be a couple of edge 2-cycles, a couple of corner 2-cycle or in the last case one corner 2-cycle and one edge 2-cycle. Currently, I first solve corners with 3OP, and if I need parity fix, one corner 2-cycle and one edge 2-cycle, I use the T-algorithm to finish the corners and I would have memorised the UR and UL edges swapped. If I have to solve two corner 2-cycle I use twice the T-algorithm with the conjugations to compensate both edge swappings. And finally M2 for edges. If I have to solve two edge 2-cycle, I need execute M2 six times, three per cycle. But I don't like very much this method and I think it is not very appropiate for commutators that I am trying to learn.

Lots of questions...
1. What is the difference between 3-cycle and piece by piece BLD methods?
2. Which is more efficient?
3. How do they allow you to solve the cube blindfolded and how do they work?
4. Does M2/R2 do edges first then corners?
Just FYI, I know very little about BLD, so if you explain in newbie terms, that'd be great. I am reading this site:
http://www.ryanheise.com/cube/corner_3_cycles.html
to get more info, feel free to list any others that you think might help.

3 cycle is using things like u perms to solve two pieces at a time. piece by piece is like m2 you only solve one piece at a time

There is a lot to explain for your questions. If you haven't read Macky's page before, it may help you some.
I can answer these two here. 3 cycle methods use 3-cycle algorithms to solve the permutation of 2 pieces of the cube at a time (usually). 2 cycle methods use 2-cycle algorithms (stuff like the T-perm or the slice move M2) to solve 1 piece at a time (usually), plus a side effect that disrupts the cube a little bit in a manageable way.
As to which method is more efficient, there's not really a good answer to that. Both methods have pros and cons.
3-cycle methods:
pros: solves pieces in fewer moves, usually.
cons: more thought intensive at each step, can have more "difficult" cases than 2-cycle methods
2-cycle methods:
pros: less thought required. Moves can be generally memorized before-hand more easily than for 3-cycle. This can lead to "muscle memory" execution, which can be very fast.
cons: usually requires more moves to solve all pieces. A fast turning speed will often be required to get good times (but the muscle memory execution can facilitate this to some extent).
As for how these methods are used to solve the cube blindfolded, try reading Macky's guide in addition to Ryan's guide and see if that helps.
Happy (BLD) cubing!

Joels tutorial is IMHO the best text based tutorial on Old Pochmann (piece by piece)
Zane recently put up some great video tutorials on Old Pochmann and M2

re: 4
M2 is an edges method (piece by piece)
R2 is a corners method (piece by piece)
you do the math

Looking to do 5BLD at USNats. Corners, x-centers, +-centers, wings, midges: OP, comms, advanced M2, advanced R2, advanced M2.
That has been my order, but I could change it up.
What do I need to know about parities and stuff before I attempt? Thanks.

The implementation of commutator 3cycles based off of M2 ex:
DF-UR-BL U' {M2} (U' L U) {M2} (U' L' U') U Here is a video By Zane

My advanced M2: using 1-move setups to transform edge cycles into 8-move comms with M2 as the interchange move. The setup is always a U* move (to bring UL, UR, or UF to UB) or a B* move (to bring LB, RB, or DB to UB).
Also, using 8-move comms when one of the targets is FU or BD (using M or M' as the interchange move). But, I don't use the first strategy to setup to the second strategy.
