Thoughts on dominant hand

[Smiles]

For the sake of this thread, everybody in the world is right handed.

If you've ever tried to be ambidextrous with only mirrored algs, you'll know what I'm talking about: regrips to switch between hands is terrible. If you get a right handed OLL and a left handed PLL, there's this uncomfortable switch in between.
What I've noticed is that the left thumb is almost always on F because you want your left hand to do U' flicks. Makes sense.
From LS to OLL to PLL, it makes sense to keep your left thumb on F as much as possible while your right hand does any wrist related things, including regrips in order to start a new alg.

A perm and E perm begin with your right thumb on F, while the left hand does a regrip.
(Btw there is no true cube rotation because R' x is just l', and R x' is just l)
Wait, you say! If your right thumb is on F, that's taking the role of the left hand. If your left hand does a regrip, that's taking the role of the right hand! In this case, doesn't it make the most sense to do A perms and E perms left handed?

And that's what I think makes the most sense, at least on a 3x3 where wide turns are easy.

Don't like lefty algs? You can trick yourself into thinking a lefty alg is actually righty.
E perm = r' U r F' r' U' r F r' U' r F' r' U r F
A perm = r U' L D2 r' F r D2 L2

just remember to do all the F/F' turns with your ring finger for E perm.

I only noticed this because I had mirrored A perm algs in order to reduce AUF and therefore 50% of the time I went lefty and 50% of the time I went righty for A perms. I always liked the righty ones better and realized it's because there were no regrips.

I like this a lot, but I dont have uncomfortability switching between left and right algs. In fact, sometimes they seem to flow better for me. I dont know why this is, but they flow well for me, maybe because I tend to keep my left thumb in the bottom left corner of F instead of on the center piece.

You could just use algorithms like these:

A Perm (Put headlights on left): x R2 D2 R U R' D2 R U' R

E Perm (Switch Vertically): x' R U R' D R U R' D' R U R' D R U' R' D'

I can execute both of these sub-1 during a solve as well.

I always interchange between hands. But I'm slow. Anyway, just use different algs.

I use these algs too, they're the same concept as the standard A perms. they require a left regrip and right thumb stays on F. if u were just as fast at the mirror version of E perm or any A perm, you should theoretically find the left version faster in solves.
this is because standard righty algs have your right hand regripping and left thumb on F, while these are the opposite.

I'm not sure you understand. What I'm saying is that A and E perms should be done lefty as the standard because of how you grip the cube before an algorithm starts.
Switching between left and right is not what I'm talking about.

 

[Dene]

A and E perms should be done lefty

Switching between left and right is not what I'm talking about.

Could have fooled me

Could have fooled me

lol i see what you mean.
switching hands in general is not what i mean. i mean specifically use mirrored algs for A and E perm because they feel more natural. no hand switches happen. if anything, a hand switch happens if you use the standard A or E perm because of regrips.

The problem I have... you keep making it sound as if there's only one way everyone does A perm and E perm. I use the same algs, but I perform them in very different ways.

And also, you don't seem to know what "lefty" means. To be "lefty" is to be predominantly LUF, rather than RUF. In the two algs you wrote down, I only see two Ls in the whole thing.

He wrote those lefty algs like that to make them look like righty algs on purpose:

I assumed that when i said lefty A and E perm, then you would know I mean the mirrored version. I didn't think I needed to actually provide the mirror alg in its original form, so I gave the manipulated right hand "version" which is exactly a left handed alg.

In case you're not convinced,
r' U r F' r' U' r F r' U' r F' r' U r F = x' L' U L D' L' U' L D L' U' L D' L' U L D
r U' L D2 r' F r D2 L2 = x L U' L D2 L' U L D2 L2

you keep making it sound as if there's only one way everyone does A perm and E perm.

If you don't perform A and E perm the same way as everyone else, then this doesn't apply to you anyway.

And whether you go x' or x and do A perm from all different angles, as long as you use a variation of the standard commutator A perm, then my argument's logic still works if you go check the OP.

Ah yes I see what you mean now. I didn't really read your original post that closely so I got myself confused . And I got thrown off by things you said like

What I'm saying is that A and E perms should be done lefty

Anyway, my overall thoughts are that probably most people would rather re-grip than do lefty algs or awkward psuedo lefty-righty algs.

yeah if people already do it righty, probably no sense in changing. but it seems to make sense to teach new 3x3 cubers the lefty algs.

I'm lefty completely but I used both the right and left A perms and I can execute both E perms at equal speed. I always preferred the right one in solves even though I could execute them at the same speed. the regrip thing is why, and I thought itd be more optimal for our hands if we all did it.
