square-1 edge permutations

[AlanAlanine]

hey

so I'm learning square-1 by lars' method.

i'm ok with everything except the last step, edge perms.

is there a good way to move toward an intermediate last step?

i know how the equivalent of a Z perm (or switches UF, UL and DF, DR without set up moves), and H perm (UF UB; DF DB -- x2 for H perm), I can use a commutator J perm equivalent to do 3 edge cycles (per Thrawst's method) and I know UF <--> UR parity.

what algs would you recommend that I learn to improve my edge perm, until I learn all of the algorithms?

do you recommend completing the bottom layer first then the top for a sort of two-look edge perm?

thanks

A thread I started a few days ago.

Yeah, I'm in a similar position to you. I'm planning on learning ~8 EP algs (U twice, Z, H, UF UR parity, UF UB parity, and the other two cases which have parity). I can use one of these to solve one layer, and then flip the layers over and solve the other one.

I only know
a) both U-perms (on top and bottom) semi-intuitively by doing what seems to be the same as your 2-J-swaps
b) A studied straight parity fix on top
c) Z and H intuitively on top and bottom

wouldn't you consider that an intermediate last step?
