CFL is an adaption of CFOP to FTO. I first presented this idea in July 2024 in the FTO Discord server. The method also shares some similarity with the Nautilus FTO method with its first two layer triple step. In comparison with Nautilus, CFL provides more freedom with many more options during F2L, but possibly requires a bit more look ahead effort. Maybe we will see a sort of merge of the two methods in high level solving where solvers use block building to solve the first two layers using various techniques.
