@Jason Green , You must correct your preinspection and cancel y2. After it the solution works fine. :)

Thank you, actually z2 y2 is how I did it, which equals x2. Leave it to me to mess up notation, especially rotations. I still don't remember those correctly when I see them. :)

Nice job, I've still only got sub 2 once (maybe twice?).

@Jason Green Great solve man! I bet that felt awesome. That's faster than my PB single!

Thanks, it did! I'm not sure how to feel about beating your PB, I think just lucky. :)
 
@mafergut: The first thing I did when I got mu AoFu GT was to whipe away almost all factory lube, after that I have not added any new at all.

Gigaminx ... nothing new there, just two trash solves today :|
Square-1 ... a5 PB! 15.947, 16.127, (15.085), (18.730[p]), 15.378 = 15.817
 
@mafergut Ah I didn't know you were new to 7x7. I'm still really slow, my PB is 9:42 so I wouldn't say I can speedsolve it yet either. For the last two centers I almost always use commutators for the last couple stickers, don't feel bad about that. I have a mini ShengShou and the original pillowed AoFu and I can't say I really like either of them. I prefer the cubic shape of the ShengShou, but the AoFu turns much nicer. So I guess I'm hoping the AoFu GT will be the best of both worlds :)
 
@Selkie have you lubed or tensioned that Megaminx? have it improved after breaking in?


Almost 75 tries at corners BLD, only 12 successful ones so far, maybe I shouldn't rush them, but it's nice when I get a good time. I'm starting to do also impossible cases, with setup to possible ones because I don't know those algs yet, it's tricky, first one was a success, but I was probably lucky.

Well, not only new to 7x7 but I don't have a 6x6 yet either. I suppose what I did for those last stickers is a kind of commutator. Do fast people learn specific algs? Would "half centers" be easier? Also the 5-piece edges seem so large... For the last 2, as I didn't know what else to do I just fumbled around with 4x4 last two edges alg slicing at different levels until I got them right. I have never cared to learn specific algs for this in 5x5 and I assume that for 7x7 there must be lots more cases. How do you guys approach that? I feel like a beginner asking how to do the cross.

@mafergut you can avoid conmutators on last 2 centers most of the times and when you can't avoid you just have to do one, just when the last center is an oblique center and to solve it just do a niklas.

The way you should approach L2C is middle bar, then inner or outer bar, then the one you didn't pick (outer if you picked inner, inner otherwise), then the remaining inner bar and lastly the last outer bar. corners and centers of the bar work the same way as in 5x5. There's a good tutorial in http://cubeate.es by Alberto Masó

other advices I'd give you are:
  • Be color neutral
  • Concentrate on moving fast all of the time, the solve takes a lot of moves and you can shave a lot of time just by not being relaxed
  • Try to get advantage of already made blocks by pairing differently on the first centers
  • in freeslice just pair anything that you can see, don't search for the best case, save the already paired edges on the same side until it's done
  • In last 4 edges try to get 2 pieces ok at the same time pushing a misoriented edge with a good edge so when you swap the edge and insert it back it's good.
  • Practice 3x3 on 7x7 to get used to it and break it in.
That should take you to my level (barely sub 8) or even pass me.

I didn't learn any new algorithms for 7x7. For centers I just pick a colour with a good start and build the center bar first, then intuitively build and place one bar at a time. Then commutators if there's a couple stragglers at the end of L2C. For the last two edges I use the tried and true slice/flip/slice back method (same as 5x5). This will either solve them both, or reduce it to one edge with parity (or double parity) which you use the same alg as 5x5 to fix.

Remember with 7x7 edges, when you do the slice/flip/slice move, you can slice just the 3rd layer on its own. Here's an example: https://alg.cubing.net/?puzzle=7x7x...;3u-&alg=3-3u_R-_F_R_F-_R_U-_R-_3-3u-

For me, if there are new algs for these steps there's really no point in learning them until I'm much faster. At this point look ahead, turning accuracy and TPS are way more important for getting faster.

Ah. I used to do the wrong edge placement based on the first Yau tutorial I saw but then changed. I thought I was a bit ahead of everyone but went to a comp and several people hadn't even heard of the old method.

Oh! Are we talking about 4x4 here? If so, I still do the old method, and hadn't realised there was a good alternative... Can you give a quick idea of how it works? You put the three edges in the right places, and then when it comes to the fourth edge, how do you avoid messing up the centres?

You just slice set up the pair, slice back, just like you would do with last 8 edges.
 
I think you guys can see this, I did a live stream reconstruction solve of my PB on FaceBook. Then I did some more solves including a 4x4 and (yikes) 5x5 (7 minutes+, did I say how slow I am at that?).

I'm thinking of live streaming from the comp Saturday some. For some reason even on my work iPhone I cannot save the HD video though like some people can. So I'm torn whether to live stream which is fun, or record normally so I have HD... First world problems. :)

@earth2dan: I know use a Tanglong as main and a YueXiao as backup. The Yuexiao is very nice, fast but quite stable at the same time. I just have some issues with the corners causing lockups at times and with the low turning resistance, which makes me misalign a layer without wanting by just barely touching it but this is not as serios as in, let's say, a Meiying, where it is almost as if the dang thing was moving by itself. Anyway, I prefer the Tanglong because it's more stable and once broken in it is so buttery smooth, even though it requires a bit more force to turn, which adds to the stability.

@Jason Green: Nice video!!!! I wouldn't dare to livestream myself

Yesterday, second solve with my Aofu GT. It took a bit less than the first but I'm sure over 20min (it was untimed and "relaxed"). Still having problems with the last 2 stickers in the L2C, a bit less issues with last 2 edges. I had to apply the parity fix for the last edge but it was, as you said, the same as with 5x5. Still so far from even sub-10, I guess. Will try to solve it a bit more this weekend and maybe even time one solve, but I'm afraid to do that :(.
 
@Jason Green - I like the livestream :)

@earth2dan - Wow that took a while and I am complaining about a parcel that isnt here that I ordered 2 weeks ago :)

@mafergut - First few 7x7 solves will feel very long and to be fair the puzzle still feels clumsy in my hands but persevere and your times will drop :)

@muchacho - I tried loosening the Dayan megaminx quite early on but it started popping centres with the screws so I tightened it back up! No lube at all and it is beginning to feel very, very nice. Will probably dismantle and lube the core and internals in a couple of weeks but I believe they break in better without lube.
 
@Selkie: Chris, thanks for your feedback on the Dayan Mega. I also see in your videos that you are using the ridged one. I can't wait until I receive mine. If it's as good as you say, my already procrastinated SS modding project will be forgotten forever :)
 
So I was playing with my new YueXiao last night and I'm not sure what I think of it. It definitely feels like it has potential, but I'm having some problems with lockups, particularly with F' moves. Out of the box it was way too loose so I tightened it up a bit, but I still haven't applied any lube. I think I need to lube the core with something heavy to slow it down a tad, as I am often overshooting.

I'll take it apart, lube it, and re-sticker it this weekend and then we'll see if it can dethrone the mighty AoLong V2. I also got a new Thunderclap to set up and re-sticker this weekend. I have a stickerless Thunderclap and I love how it feels, but I don't like it's shades so I'll set up the new one with my colours and have a 3x3 showdown :)

Then I need to just swear off buying any more freakin 3x3's until I'm consistently sub 20... Except maybe a Tanglong, I want to try a Tanglong now, thanks @mafergut ;)

@mafergut 7x7 takes eons to solve at first. Only recently, as I started focusing on increasing TPS, have I managed to get the occasional sub 10:00 solve. It's a beast, and must be tamed!

Good luck @Jason Green, @h2f, and anyone else competing tomorrow!
 
@earth2dan - Yes the YueXioa can be quite locky. @MarcelP has a video on his YouTube channel with a mod that really reduces the lockups. If you really don't want to buy anymore 3x3 then really, really don't buy an X-Men Tornado. Its awesome ;)

Yes best of luck at comps @Jason Green and @h2f . We will await results with interest.
