Y perm vs. J perm corners

[fanwuq]

I've been thinking about switching from 3OP corners to Y perm corners. The problem is that Y is not exactly my favorite algorithm. It is way to long. I looked on Joel Noort's page and he actually lefts off the F and F' at beginning and end. That messes up my muscle memory. I like J perm a lot. It's almost like Y. The same, except it switches adjacent instead of diagnal corners. Why don't people use that? Is there some obvious flaw with J that I'm missing?

Here are the Pro's and Con's..

Y perm
PRO: Easy and fast to preform, along with minimal setup moves.
CON: more places to shoot.


J perm
PRO: Easy and fast to preform, also only 7 places to shoot.
CON: You have to orient corners first.

A couple of things..

First, Daniel, You don't have to orient first for J perms. I use J perms throughout my solve alongside Y perms, as I see it fit. The problem with J perms is that you have 2 positions that you can use. Depending on the piece, one is almost impossible, while the other is very simple. The point of using the Y perm is to utilize the fact that both the R and F slices are free to move the piece into. Wuqiong, when I initially learned Y perm corners, I set up everything to a Y perm, not to the conjugated one without the Fs. I just was able to see the set-ups better, since I tracked the BU stickers to the FU stickers. Almost all of my set-ups are the same, except for a few tricky ones. BLD solving requires understanding of the cube, and its really an individual process. Learn how you feel comfortable and it'll make you faster than trying to force a method that doesn't fit you right.

Both = ftw.

 

[fanwuq]

Thanks, I guess I'll use both.
I may also use this alg: F' U F R' D' F L F L' F2 D R
that is on Erik's site.
I'll practice this more and see what's more comfortable.

How would you start a new cycle?

 

[joey]

Just pick another corner, and go again.

Instead of Y try my V, I think it's faster:

R' U L U' R U R' U L' U' R U2 L U2 L' ... Niklas for the 6 first turns

Mirror and reflections does the same work.

 

[fanwuq]

Hmm...
I've forgotten about V perms. I used that a lot to correct parity when I used to use 3cycle. I don't know if the set up is as convenient as Y.

 

[joey]

No, V-perm is stupid to use.

 

[fanwuq]

I tried several sighted solves using both J and Y perms. I'm starting to like it.

V-perm? That's a terrible choice as compared to Y and J. For parity, sure why not.

 

[Harris Chan]

Yah, using both can minimize the set up move to like 1 move lol (nah may be 2 max)

 

[fanwuq]

I just used Y perm corner in a speedsolve to do a 1LLL.

This method is so awesome!!!!!!

I did 50 solves on 2x2 today using this method.
I can memo 15-60 seconds as opposed to 35-150 seconds with 3OP.

Average is 1:23.14, 38 cubes solved out of 50. I was careless on the last few.
best time was 35.26. Best RA was
Average: 1:17.39

Standard Deviation: 23.32

Best Time: 35.26

Worst Time: 2:11.27

Individual Times:

1. 52.51

2. 1:43.32

3. (35.26)

4. (2:11.27)

5. 57.45

6. 1:24.31

7. 1:24.31

8. 1:28.26

9. 1:53.81

10. 1:27.44

11. 41.36

12. 1:01.13

Hiya, umm I only use this J perm conjugation for the last corner in parity, but uhh.

L'U'L F2 R'DR'D' R2 F2

Which is pretty sweet because combining this with the left and right handed Y perms you can do all of the single corner permutations with a 1 move setup.

Of course, You can solve 2 corners at a time with a 9 move average using other methods ... soo meh ...

What method did you use to memo and did you orient first or no?

So where would I go to learn Y/J-perm corners ?

Thanks a lot.
