Fingertrick question

[Carson]

I am having difficulty with the clockwise A permutation algorithm. PLL algorithm #1 from cubewhiz.com
(l' U R') D2 (R U' R') D2 R2

The D2 fingertrick is causing me a ton of grief. I am using my left hand for the trigger. I have watched both the slow and fast video demonstrations on cubewhiz, and I appear to be doing it correctly. My problem is that I tend to lose control of the cube while doing the trigger. I frequently either start to drop the cube, or it becomes unstable in my hands and I make an unintentional move. I have performed this algorithm probably 300 times during the last couple of days, mostly at a slow speed in an attempt to feel comfortable with the moves... but I still do not feel like I am "in control" of the cube even when going at a slow pace.

Any suggestions? Is it perhaps something to do with grip, or is this just one of those things that feels awkward even when performed correctly?

You mean that you are doing it the same way as Bob. There's no single "correct" way to execute an alg. Blindly copying the exact movements someone else does isn't necessarily a good idea, people are different. If it doesn't work for you, try something else. For example, this might seem easier: l' U R' z' R2 U L' U' R2 U2

Or as I do it: x U' L U' R2 U L' U' R2 U2

I suppose my wording was a tad misleading. What I should have said is that I appear to be doing it the same way. I was already doing the same fingertricks/movements before I watched the video. My entire reason for watching the videos was that I believed I must be doing something strange. I was a bit suprised when I found that my movements matched the video almost exactly.

I wouldn't be that concerned, and would simply find a different algorithm to use... but when this is broken down, my problem is really with D2 triggers. I have just begun OLL/PLL so I haven't had to deal with that many of them, but looking ahead, they are something that I will need to be comfortable with.

I'm sure this is some little problem with the way I am holding a certain finger, or finger placement on the cube, or some otherwise insignificant detail... but I do not know any other speedcubers in real life so I don't have the opportunity to get first hand tips and evaluations.

Maybe someone else has run into a similiar issue at some point?

Yes, aspecially if you like to learn commutators because these often uses D2 to swap pieces. For real that is exacly what your alg is, a commutator that uses D2 to swap two of the corners. That is done twice to create a 3-cycle, the rest are setups and restore turns.

When doing D2 commutators I mostly do D2 as two separate D, either D D using left hand or D' D' using right depending om the current grip, try that

Probably not the fastest/most efficient way to execute it, but it's fast/easy enough for me... especially with my arthritis ... x (R' U R') D2 (R U' R') D2 R2. Everything done with the right hand. (R' U R') is very fast. For (R U' R'), do U' with thumb immediately after R, and for R', index finger pulling back (it's a fast trigger). Personally I find it faster to do it this way rather than trying to use my left hand ring finger to do the D2's.

 

[Aub227]

sorry to repost,but I forgot to mention. Since all is done with the right hand, you left hand is pretty much stationery at all times and you should feel very much "in control" of the cube.

Try http://cube.garron.us/MGLS/?page=PLL.htm&case=PLL5&alg=428; maybe you'll like it.

If you prefer u2, you could try
(l' U R') u2 (L U' L') u2 R2
lU'R u2' L'UL u2' R2
...

As for D2, almost everyone I've seen does a full grip for speedsolving. But watch Matyas' big cube BLDs for a bunch of fantastic ring-finger D-turn action!
