[Help Thread] Edge Control

It's VHLS.

But really. Full edge control for LL from standard CFOP is just a waste of time. Whatever algs you learn for some awkward insertions are not going to be better than a quick F sexy F' or the like.

It's not a waste of time. There's only 8 cases (including R U R') when the pair is already made and only about 3 are awkward at first, but once you get used to them they're fast. I would recommend just learning the ones with 0, 2, and 3 good edges showing and then only learning the other three if you feel like it. But I will agree that if you make the pair using the R of R U R' then it's usually just faster to do 2-look OLL.

It's a good idea, but is it feasible to use in a solve? That is the question. Here is the video explaining the idea from Josh Lewis on Youtube.

LEt me know thoughts etc, from the community.

As with many subsets, in many cases, they're very useful. In other cases, it's much easier to learn a VH case or just skip EO all together. It's a useful thing to know, particularly for OH, but not something to do every single solve.

I was considering in context with CFOP, because the edges will already be oriented after completion of F2L in ZZ.

I was not aware that you use ZZ for OH, I was assuming you used CFOP. For 2H CFOP, it often wastes too many moves and too much time to be useful, but sometimes it's useful in easy cases.

So much like X-Cross, if the cases present themselves, execute if it won't overload move count too terribly much?

Precisely.

When do I gain advantage for using sledgehammer f2l insertion?

 

[TDM]

You can orient edges with it, which can give you better LL cases.

 

[AlphaSheep]

When the edge in the F2L slot has the U sticker facing the right, and you want to insert the pair with R U' R', check the edge in UL. If its U sticker is facing left, then inserting with U' Sledge will orient those two edges.

Or, simpler, if the edge in the slot is flipped, inserting with sledge guarantees that you won't get a 4 flipped edge OLL.

Oh thank you this is very helpful

If you want to be really fancy you can also use it to orient F2L edges to avoid rotations.

Thats maybe bit too advanced for me But thats pretty neat!

Pretty much all the discussion I see of edge control seems to assume the pair is being inserted to FR. I solve to all slots, front and back. Do people use edge control on back slots? I assume mirroring edge control or WV, VHLS etc to FL is easy enough, but what about the back slots?

I mirror some things to BR. Simple things like sledge for orienting edges, and 2-gen WV cases. I don't usually do anything in BL.
