So, it's like Petrus, except instead of EO you do CO. Then, when F2L is finished, you have all the corners oriented. Then you can do one alg and solve the rest of the cube. The LL set would have less algs than ZBLL, cause corners instead of edges would be oriented. I can't figure out how to do CO properly though.
CO is a pain XD. ask WoowyBaby about how to solve it, he's an FMCer who uses domino reduction sometimes, he'd know.
Petrus with CO would make the right block F2L blockbuilding a whole lot worse, because with EO you can do it iwth just R and U moves, while without it you require F and / or B moves, and, also, it is basically impossible to building your right block without breaking CO.
CO isn't hard to do. In fact, it takes the same number of moves to do as EO, but the benifits of CO aren't much. It doesn't make blockbuilding any easier like EO does and it barely makes the corners any easier to solve, and it heavily restricts what you can do, for example, if you have CO it's impossible to solve the cube without breaking CO, unlike EO, unless........ along with CO you also have EO on two axis as well; so then you have domino reduction. Then it's actually really dang good
