Abstract	The requirements on the Final Focusing System (FFS) for a new linear collider has lead to lattice designs where chromaticity is corrected either locally or non-locally. Here, alternative proposals of lattice design are presented for the current CLIC 500GeV beam parameters, combining the local chromaticity correction on the vertical plane and non-local correction on the horizontal. The tight tolerance on phase advances and beta functions imposed to obtain -I transformation required to cancel the chromatic terms is relaxed by enlarging the system length and using a more general transformation definition, aiming to obtain better results in tuning simulations.
