Weird "fingertrick" with A-Perms

[ajmorgan25]

I've noticed in the past that people seem to use an unusual "fingertrick" when performing A-Perms with an algorithm similar to x R’ U R’ D2 R U’ R’ D2 R2. The specific moves I am referring to within the algorithm are both of the D2 moves. Instead of fingering the D2 moves, I see a lot of people (even the WR holder I think) wrist the D2 moves which seems pretty inefficient and slow to me. I've always thought it would make much more sense to "double flick" the D2 move with your pinky and ring finger similar to a double flick move that a lot of people do with U2 moves with the index and middle finger. I don't know if there is any sort of explanation to this other than preference, but it seemed kind of interesting to me.

This wouldn't be as interesting to me if it wasn't for the fact that a lot of cubers, including myself, go out of their way to practice unusual and unnatural fingertricks to benefit the execution of their algorithms in the long run. I'm mostly referring to algorithms with M or M2 slices that most of us taught ourselves to use our ring and middle finger to execute.

If this post was pointless and stupid, I apologize.

Do you find it natural to do that? I only tried it a few times but couldn't get it to seem even vaguely efficient because my pinky and ring fingers aren't as agile as my index and middle.

Personally, I double flick my ring finger at that point in the alg, but I don't have an especially fast A-perm so there may be a better way.

I found the double flick of my ring finger more natural than a double flick with the ring finger and the pinky finger, but I still found both more natural than the wristed turn.

I do it with my ring and middle

Well my A-perms aren't extremely fast, but they are easily sub 1.5... So wristing isn't too bad. I believe it is just a matter of personal preference as you stated.

For the A perm, I do D2 with a pinky-ring double trigger (sometimes). I know Rowe uses a double ring finger tap but I can't do that fast and I have no idea how he gets like .8 A perm with that :O

 

[Faz]

Personally, I use the U2 A perm, where you do an x' at the beginning instead of X.
My anticlockwise A perm is sub 1. (The lotsofsloths one)

I wrist it and I find it a lot more efficient. When I'm solving for fun I do the ring/pinky trigger, and it falls into some timed solves. So I should stop doing it because it's extremely uncomfortable and inefficient for my style of speedcubing.

Also using your wrist would seem more adaptable to big cubes to maintain more control and stability.

I use my ring and middle finger as a double trigger, and it's very fast/easy for me. Also, does anybody know how some japanese cubers do one of the A's? It looks really different than the usual A perms, with R/L/U moves and a rotation or two.

I know a lot of fast cubers wrist that one, but it goes against everything I know about fingertricks and speed and I double-flick it, for better or for worse.

Breandan Vallance has a very odd A perm:

lU'Rz'R2'U'rBR2'yR2

but you should watch this:

at around 1:31 to see how he does it.

I personally do:

ccw: R l U2 R D R' U2 R D' R
which is reasonably easy to sub one once you get used to the D and D' fingertricks.

for the cw one i just do the 'normal' alg, and wrist it. To be fair, I normally do a bit of a z' turn to make it an R2 rather than D2.

 

[mazei]

I do it as x'UL'UR2U'LUR2U2 and reverse for the other one. If not I will use the normal one and double flick with my ring and middle.

 

[rahulkadukar]

It does not matter if you wist it as long as you are fast WR

 

[4Chan]

Yes, I too have noticed this. I for one, also wristed mine for the longest time, even into sub 20.

With my A perm, i don't have to do a double ring finger motion.

I do mine like R2 B2 R F R' B2 R F' R
The same algorithm, except from a different angle.

I do a vertical mirror of the algorithm you wrote in your post, so I do a U2 instead of a D2 and of course a D instead of a U and vice versa. That seems more natural to me. But I do agree with you though, doing a D2 is much faster and more natural when done with the pinky and ring finger instead of wrist turning.
