My advice would be to keep learning at the rate you are doing so already. The dot cases are amongst the OLLs where a one-look alg is most beneficial and the dots are only worth avoiding during an R U' R' style insertion (e.g. doing R' F R F' instead).

Makes sense! I need to give the recent new algs I've learned a while to sink in, but as soon as I feel ready for it I'll start looking at the dot cases as welll.

I've seen that one. It's for a 7x7 though. Unless I missed the 4x4 spmewhere

There is some confusion over Speffz on bigger cubes as I think most people think the first piece that uses the letter is the corner but those pictures say otherwise. On 4x4 it's simpler as you are choosing the 2nd wing clockwise after the corner so in WCA orientation white/blue is A (Ubr) and blue/white is Q (Bur).

@mark49152 @h2f @newtonbase

Feeling pretty dumb. I can't seem to wrap my mind around how to assign letters to wings properly. I've looked for an image of a lettered 4x4 as reference but can't seem to find one. You guys know of any pictures?

EDIT:
I think I've somewhat figured it out. Just need clarification. Am I right to say that only half of the wing stickers will have assigned letters?

Yes, only half the wing stickers are used. For each pair on a face, it's the clockwise-most that is used, if that makes sense. You'll see that it's impossible to get the other sticker into the UB interchange position.
I'd recommend Noah's tutorials if you're still having problems.

@Selkie, just had an email from theCubicle saying no Valk Ms will be made until Chris gets back from wherever he went for Chinese New Year. My Valk (non M) has been delivered, lets see what happens first - me getting my arse in gear and buying a few magnets and some glue (already bookmarked in my browser at home) or Chris getting home, spending a few days catching up, working on some other projects, magnetising a QiYi 7x7 for lols, catching up on the backlog of GTS Ms, inventing a new type of sticker that never chips, catching up on the backlog of Valk Ms, then USPS international shipping getting it to your door.

My money is on Chris!!!

My wife is away tomorrow night. I might treat the kids to an early night and magnetise something. GTS or Valk?

Correct, in 4x4 only one sticker per wing has a letter assigned because each peace can only be in one position, I mean, if you try to "flip" a wing in a 4x4 you also move it to the other wing position in that dedge. Does this make any sense?

By the way, good news and bad news for me. New 4x4 PB Ao50 1:16.36. Coming close to 1:15 but long way to go to 1min The bad news, @Logiqx, is that so far my findings are that the bad batch had white internals so I will most probably have to buy another WuQue from a reputable store like SCS or theCubicle Any other options?

Thanks @newtonbase @chtiger

I already watched Noah's tutorials but only once. I planned on watching them over a few times more but must wait till I get home. No WiFi at work

I managed to understand the lettering scheme so far with your help! Now I'm working through how to set up and execute with U2 and r2

I vote on the Valk. Better cube all around

Also, to @kbrune I learned the little theory I know about 4BLD from Noah's tutorial. I say theory because apart from some partial sighted solves I have never ever tried a real 4BLD.

I don't quite understand why it works that way. But I do understand how to letter it and how to follow the targets now. Which is a good start. Still feel dumb with 4bld but that's ok. There was a time where F2L seemed like I'd been dropped on a planet in a new universe. I'll get there!

For r2 you can do all algs except the ones with M/M'. For targets on l layer you setup everthing to BUl and do the alg for BU from M2. That's all you need.

R2 is very easy if you know M2. The only difference is that C, W and K set up to Q and the parity alg is new. Also you can't use Noah's shortcuts for N and H.

Do I execute the BU alg on the l slice? Or on the 4x4 at the 3x3 stage. As in performing lr2 like M2

I'll have to revisit this as my lettering is non speffz.

My only concern about the Valk is that the pieces are a nightmare to take apart.

It's the same setup as on the 3x3 then R2 instead of M2.

It's the 3 pieces on the l slice that can set up to Bul with l moves so Ulf, Fdl and Dlb.

The BU alg I use for 3bld is
(U M' )*3 U M (U M')*4

will that work?

You mean the corner stem thing? Any tips? Not just for disassembly, but in general. Will be using DMCubing's tutorial off YouTube, and 4x2mm n35s.

I don't think so. I do B' R B U R2 U' M2 U R2 U' B' R' B

No. I used: (B' R B U R2 U') r2 (U R2 U' B' R' B) and the same when I was M2 user.

Yes, the end bits are tricky and I worry about breaking them. The cube I did was capped so quite different to most.
I'd just suggest that you pay keen attention to polarity and stay organised.
