Ambidexterity on PLLs & other algs?

[Arkwell]

Guys, for my PLLs right now I use Feliks's Cubeskills PLLs. There are 4 PLLs where you would have to do a U2/U2':
E-Perm, Jb-Perm, T-Perm, V-Perm & Y-Perm.
My solution being I'm easily ambidextrous is:
E: x' (L' U L D') (L' U' L D) (L' U' L D') (L' U L D) x
Jb: (L' U' L F) (L' U' L U) L F' L2 U L
T: (L' U' L U) (L F' L2' U) L U (L' U' L F)
V: (L U' L) d (L F L2 U) (L U' L F') L' F'
Y: F' (L' U L U) (L' U' L F) (L' U' L U) (L F' L' F)
So i'm basically mirroring the original algs. I just saw a Youtube tutorial whereto poster said that doing that is a 'beginner' way for a PLL from a different angle because he believed that you should pick a hand to stabilize and the other to turn and do the algs. My question, if doing algs comes easy from any hand (Any new alg is automatically learned with both left & right hand) shouldn't I have that as something in my arsenal as an advantage or should I just pick one hand to turn, one hand to stabilize?
Please feel free to shorten and or move this post if necessary.

Many thanks.

As long as you do the same finger tricks and do some timing tests to make sure doing the alg with the non-dominant hand is faster than U2 Alg U2 then it’s fine. I do it and some really fast cubers like Tymon do it.

I can do these plls with both hands: G, U, T, Y, J, R, N
the others I never practiced

OreKehStrah, many thanks, you've helped me more than you know simply by answering the right way i.e. "As long as I do the same fingertricks (I do) and as long as doing the alg is faster than a U2/U2'". The reason reason I used my ambidexterity is because as a beginner working on my U2/U2's It just came easy to do all algs with both hands from the beginning. I got this habit from my music teacher who me the reach I had on piano and guitar should be worked on from my beginnings not something to regret later. Filipe, I have to say though, anything in isolation is not going to magically make me a threat to any fast cuber. The best cubers have many things working together to put them at the top and I'm willing to bet that as I get better I will find other ways to avoid U2s going from Cross to F2L, F2L to OLL, and OLL to PLL. In Feliks Zemdegs Instagram with Anthony Brooks Anthony talks about one of Feliks's drills where he tries to predict what PLL he'll get coming off his OLLs so I'm sure as I get better I will find better ways to avoid U2s going through CFOP. Right now I'm having fun with my ambidexterity but I'll keep you guys posted as I get better and find new ways to go from C to F to O to P.

Thanks guys!

Threadbump:
Although mirroring is bad, it's reasonable for the y2 angle.
Many people say that LUD Gc is the best for that angle which is not the case. RUF is clearly better than LUD even if it has a starting regrip and here's why:
For a right handed CFOP solver, most of the OLLs will be righty dominant hence, switching from RU* gen turning to LUD will surely have a grip shift in between. Moreover, the starting regrip in RUF can be eliminated by doing rolling R2. Hence, R2 F2 R U2 R U2 R' F R U R' U' R' F R2 is better than L2 U' L U' L U L' U L2 U D' L U' L' D for the angle.
This is my opinion. You can have different opinions of your own

This is too general in my opinion. The blanket advice that mirroring is bad is simply out of date, and not true. Mirroring is only bad if you are only good at one side turning, IE righty and not lefty turning or vice versa. A lot of OLLs end in a neutral grip so the shift isn't always an issue, although yes there are definitely times where is would be awkward. The main point I'm making is that there are times where is is 100% worth to do lefty instead of righty and times where it is not, so the subject of ambidexterity is more nuanced than most people think.

That's definitely true.

PLL isn't used only with CFOP. It's used with a lot of other methods too. One such example is the Mehta method. In the Mehta method, almost all of the APDR algs are R2U or R2US gen and some of them don't end in a neutral grip. In this context, RUF is more useful than LUD.

That's true. However, a lot of LUF algs can be reframed in execution such that L moves are executed as wide R moves.

I average about 13.5 seconds so take this with a grain of salt for sure. I’ve been doing righty and lefty PLLs (mirroring) since I started cubing (late 90s). I always disliked the advice to not mirror, as I also find it relatively easy to learn an alg for both righty and lefty from the start.

There are times when the grip change is awkward, but at my turn speed it is generally faster than U2 alg U2. Also, some PLLs for me are faster lefty even though I am right hand dominant. T is one example, and I have timed it out multiple times over the years and it continually holds true.

One other reason I mirror is that I have repetitive stress injuries in my right hand from cubing and have for years (carpal tunnel probably). If I make my cubing entirely right handed it makes my wrist hurt sooner and more and my recovery times longer. I’d rather offload a lot of my cubing to my left hand and reduce the repetitive stress effects on my right hand, even if it makes me slower (which is still debatable?)

I don’t have data on this, but I have always suspected that the advice to never mirror is bad advice. Sometimes grip changes are awkward, but I agree that the issue of mirroring is more nuanced and not so black and white as “it’s the best and always do it” or “the worst and never do it.”
