Petrus LL variations?

[Poobslag]

Petrus solvers,

What are you using for your LL: 2-look LL, 3-look LL, this "perfect enough" system Lars talks about here (http://lar5.com/cube/270/index.html) or something different? And what do you like about your LL method?

I tried to parse Lars's "advanced last layer" page but didn't get it. The pattern recognition for a "one look" system seems really difficult. And figuring out "on-the-fly" how to combine algorithms which both orient and position cubies seems impossible - is that how Petrus experts roll?

In the meantime I'm learning Fridrich 2-look LL which is going OK for me, I'm close to 30 seconds. I just want to know that I'm not wasting my time...

I use OLL and PLL. they use more turns on average but recognition and execution is a bit faster.

It's not too bad.

Lars' idea is to memorize a combination for each case, not to figure it out every time.

Don't focus on LL if you're at 30s. The difference between different 2-looks and 1-look when executed well is a couple of seconds at most. Just learn to do whatever you're doing now better.

Cool, yeah don't get me wrong, I'm putting a lot of effort into steps 1-4 and getting them faster at the same time. Right now my F2L is ~20 seconds, which is down a lot from last year (it used to take me 20 seconds just for the 2x2x3)

It sounds like you're an advocate Lars' "One Look" system then?

I use OLL and PLL.

 

[thelurch1986]

I also use 1 look OLL and 1 look PLL with Petrus method.

Umm no, I'm not. Using combinations of short algs when it's (almost as good as) optimal is a good idea, but I wouldn't recommend learning to do all LL cases that way.

It's never a bad idea to study something new, but not to the exclusion of the basics.

Tip for the OP: Johannes and Erik are two of the fastest Petrus solvers in the world. Listen to them.

Thanks - I appreciate the input everyone's given me in this thread. A lot more Petrus solvers use 1-look OLL and 1-look PLL than I thought. I'll focus more on my F2L and execution speed for now and maybe consider a more efficient LL approach if/when I break 20s.
