Help me find an old SpeedSolving thread.

[IQubic]

So there was a thread I had found a few months ago, and I want to find it again. It was a thread talking about N and Y perms, and how they could be made better. Robert Yau made a post in this thread where showed off this Y-perm:
F R' F R2 U' R' U' R U R' F' R U R' U' F'

I can't find it at all.
