Some days ago I found a shourcut in a 4x4 OLL. The alg is simple:Rw U2 Rw' Lw' U2 Lw Rw U2 Rw2 U2 Rw2 F2 Rw. I found out that a simmilar method exists for when you have parity, but my question is: does this method completly exist? A new way of doing 4x4 OLL. I know sunes will stay sunes, but dot cases may change. And if it doesn't exist, are there any cases that you found? I might start using this method.
