1. Petrus is like, so dead now.

I use Petrus, and I have noticed nobody is really using it anymore. I, along with a couple of other people, am like the solitary Petrus user on this forum which is still active. The majority of users seem to be CFOP, Roux, or ZZ :(. So there isn't much discussion on how to improve on specific...
2. [Unofficial] Petrus method 9.79 average of 12! Sub 10 with the big four!

8.913, 11.194, 9.539, 10.786, 9.085, (12.931), 8.888, 8.793, 9.677, 10.500, (8.341), 10.479 = 9.785 avg12 (9.119 avg5) Finally finished what I started! Sub 10 avg12 with CFOP, Roux, ZZ and Petrus! My first sub 10 average of 12 with each method: CFOP 9.85 avg12 Roux 9.82 avg12 ZZ 9.83...
3. [Unofficial] 9.71 Petrus average of 5, 8.12 single (YTUWRs)

8.37, 11.27, 9.48, (8.12), (11.37) = 9.71 avg5 A bit lucky :P It was already a 9.71 avg5 after the 8.12, but I managed to roll a 12.73 with the 11.37 so I included that solve instead. Scrambles: Cube: aolong v2
4. [Unofficial] Petrus: 11.09 avg12 and 10.38 avg5

YTUWRs with petrus, I think (7/10/2015). 9.74, 10.56, 10.56, 11.20, 10.01, 11.31, 13.34, (14.76), 10.47, 10.63, 13.07, (9.58) = 11.09 The 11.09 is my PB avg12. My avg5 PB is 9.90 First 5 are the 10.38 avg5. Scrambles: http://pastebin.com/2SSg21jB
5. Transition from EOCross to EOLine

Hello. Long time ago my solving method was CFOP, but I transitioned to a ZZ-like method, which starts with EOCross. Now I see many opinions that EOLine with blockbuilding is much better than EOCross with slots. But I see some drawbacks of those supposedly better steps: I don't know what edge...
6. Blockbuilding encouragement needed.

I'll start with some background knowledge: My main method is white cross on bottom, intuitive F2L, 2-look OLL and full PLL. With these, my personal best (no skips) is 30.56 and I average mid 30-ish. Here comes the problem: I've always been attracted to the Petrus method and blockbuilding...
