I think that Old Pochmann is for fools. The only difference between Old Pochmann edges and M2, is the that the long T-perm gets replaced with M2. that's the only difference. I think that most people can execute M2 WAY faster than the T perm.
Yes, And I like M2, but I get alot of DNFs due to flipped edges or all the centers on the M2 slice being opposite there correct locations, thats a big problem with me, so I prefer good ol' reliable Pochmann. :]
