blockbuilding/freestyle f2l (you notice i don't make a cross) + 2look OLL + PLL. anyway this was the worst solve I got on vid...i just wanted a very slow solve for fun. I average 21-22s? i think. at least my BA is 21.35s, lol.
I actually use blockbuilding for the first layer. You will notice that I don't exactly solve the Corners first in my vids. Maybe I'll post a new one soon too! Anyway, I really like your 5x5/4x4 method, and it has become my main method. I'm glad you posted the video.
