HI everyone,

Thanks to Chris for pointing out this group to me, I didn't even 
realise it existed before this morning! :-S Sorry.

The ZBLL is dependent on all 4 LL edges being correctly oriented once 
you finish the F2L. As you get further on in your solution, edge 
control gets harder and harder, simply because you have less freedom.

Recently I have been experimenting with Orienting edges right at the 
beginning of the solve. Orienting edges and then solving the cross is 
easy enough to do, but I think you would only reap any benefit from 
this if you could orient edges AND solve the cross SIMULTANEOUSLY. I 
suggested to Chris that with a lot of practice, this might be in the 
same league as solving the XCross, which Chris himself admits he can 
regularly see now given the 15 seconds inspection. I must note that 
this idea was not fundamentally mine, it was discussing this 
possibility with Ron at WC2005 and also hearing about it sometime in 
the past that caused me to try and work at it. Really, it's the first 
time I heard about it and had enough cubing experience to know exactly 
what it means for the rest of the solve ;)

Of course, most of you guys are a lot sharper than me, and you would 
probably realise even now, that if you could have 12correctly oriented 
edges after the cross is solved, you have 2 advantages.

Firstly, you can blaze through the F2L, the number of cases is halved? 
(intuition tells me this but like most things where intuition is 
involved ive probably missed a simple counter-example...). But you can 
speed through it using only R U and L (and D of course, for empty 
slots), and of course F2 and B2 if necessary. You can even use F and B 
if it's easier, as long as the algorithm is 2-generator and you 
replace the cross edge after solving the pair it won't affect the 

Secondly, once you've solved the F2L, without any work at all (and 
ensuring you haven't changed edge orientation during F2L), you end up 
with a ZBLL case by default. I realise a lot of people in this group 
are learning ZBF2L, and this would render those 300 or so algs 
redundant. I don't want to "urinate on your bonfire" by any means, I 
still think it is worth learning since my original idea of orienting 
edges is still unproved to work, but this is why I am posting about 
it! But you have to work far less hard to orient edges during the F2L, 
so you could go at it absolutely full speed, and with the ease of the 
algorithms perhaps even solve it in 5-6 seconds. However I would like 
you to consider this idea.

So you would proceed:
Orient edges + Solve Cross together

I am currently learning the ZBLL element which is common to both this 
idea and the full ZB system, so I am not in too far that I can't get 
out yet ;)

I would appreciate some feedback :)
