It can be well worthwhile combining the complex aircraft requirements into using a twin to complete the CPL. You end up with slightly more twin hours, and more importantly, you have more time on the type of aircraft that you are going to take your IRT in.
Its all rather fine pencil stuff but if the option is there to go twin early on the CPL module AND the school isn't asking silly money hourly rates then it can be beneficial.
