(Probably) a stupid question about Z perm

[blah]

If you're left-handed, U' is supposed to be much easier than U, right? Not just because of finger movement, but also because of locking-up and regripping issues, imo.

So why do people do Z perms with a U at the start and the end (you know which case I'm talking about, the one where the F and R edges have to be swapped), when you can obviously also do it with a U' at the start and end? I mean, even with the index finger "push-pull" fingertrick (the UR' at the start), isn't U'R' still faster because you don't have to waste time going back for the following U' move? (Consider U'R'U'R vs UR'U'R.)

And ending with a U sucks, I hate it when it locks up and it turns into a B', then you spend 3 seconds aligning and doing that annoying U just to realize, after you've stopped your timer, that just leaving it alone and getting a +2 would be more worthwhile.

So, why :confused:

If you don't like it, then don't do it! That makes sense right? I just start the algorithm from wherever it lands after the OLL, so it could end in a U, a U', or a U2.

 

[blah]

Actually I was talking about the case after AUF because I do my perms after AUF, yep.

I just can't understand how anyone can pick U over U', that's all.

I mean, yeah I know to you guys the time difference between a U and U' is nothing, but for me it makes quite a difference, yeah. (My Z perm takes like 10 seconds? My fastest perms are the U perms, and even those take slightly less than 3 seconds at best )

I'd say it depends on your style and what moves come before and after the U-turn.

I just can't understand how anyone can pick U over U', that's all.

Maybe they aren't left-handed?

Because (U R') is a fingertrick, that's why you do them together, if it's aligned properly, you can also do U2 instead of doing U's at the beginning and the end.

 

[Lofty]

I don't U adjust before my Z so I just align it to where my edges are going to be properly swapped using the core of the alg then do whatever U adjusts are after it.

*sigh* looks like i am going to have to dig out the z perm i use... ah yes here it is:

y R' U' R2 U R U R' U' R U R U' R U' R' U2

i though doing U's at the beginning and end of an alg is stupid, so i combined them. then i reversed the alg, i dont remember why though...

but now i of course just perform it however i am holding it, then do whatever auf is needed afterwards.

 

[blah]

Uhh, guys... You might wanna take a look at this:

...(you know which case I'm talking about, the one where the F and R edges have to be swapped)...

And @Vault312, I'd say doing a cube rotation instead of AUF is stupider (for OH)?

@hdskull, yeah I know that and I mentioned that, but I was thinking about the time lag for the following U', which I also mentioned, but never mind, I've decided it's not a big issue anymore

Sorry, I'm a retard for asking this

If you don't like the algorithm, you don't have to do it. Just because it works for some people doesn't mean it'll work for you.

If you're talking about the Z perm I think you're talking about, why don't you just not do the U at the beginning and do a U2 at the end? You can also check out other Z perms. I usually use the Dan Knights Z perm. I forget how to do the 2-gen Z perm if I do it too slowly, and I am very slow at OH.

Same here. I always mess up my Z perms and end up re-solving from F2L stage I think I take equally long to do Dan Knights' Z perm, I used to do that before I discovered the 2-gen one, maybe I'll give it a go and see how things work out, might be faster than the 2-gen since it's got less moves and my OH sucks, whether it's 2-gen or not

 

[fanwuq]

I can get sub-4 single/sub-5 average on the dan knight's Z perm. I don't even know the 2gen one.
Dan knight's alg is only 12 moves and nice fingertricks too.

umm you dont rotate it. the y is just to let you know that it is held differently than the other RU z perm. i do what everybody else does, AUF until its in position, solve, then finishing AUF

 

[Kenneth]

I don't know but probably this Z is old already but I just dug it up and it is probably OK for OH (and shorter than 2-gen's)

R' F' (U L' U' L) F R - F' (U' L' U L) F
​

I based it on two short OLL's as marked with the - and the parentesis marks the usual 4 move trigger, R's and F's are setup and restore turns.

L F (U' R U R') F' L' - F (U R U' R') F' ... the mirror
