I think FMC scrambles should always be non-optimal. If they are optimal, it actually makes it more difficult to find a valid optimal solution - because it is likely to be related to (read: the inverse of) the scramble

^Agreed.

Random Question: Does anyone else actually use Z4 or is it just me?

That 'method' from the F3L thread;

L2 R D' B2 D2 R B R' U' R D B2 F2 D' B' F U R' L D U R' U L' B'

Cross: z' D' M B L x
1: U2 L2 B L U2 B' U L
2: F2 L2 U' L U L2 F U' F
3: L U L' R' F' U2 F R

ELL: R U R' U' M' U R U' R' U' M U2 M' U' M

Interesting idea, isn't it (although I don't actually remember this being posted)?

Actually, I could see a variant of this (similar to L2L2) being potentially useful - cross + 2 F2L pairs, F2L + CO (with WV?), F2L + CP, ELL.

Oh, the *recent* F3L thread. Didn't see that one, thought Kir was referring to the older one that ran for several pages before being closed.

Wow, look at all of the heartless people in that topic.

If you were to speed solve using that method, how long would it take you?

Too long. 1x1x3 columns are not a smart move for a number of reasons.

wow I'm going to admit that writing it in comm notation made me not realize that it's two sunes.

What's wrong with "aerobics cube"? I don't understand.

Haha, nice job Dan. And even with that Pyraminx!
