You'd do the CPL on the warrior and 5 hours complex on their Arrow. Dont think they'd use the liberty.
Something people perhaps haven't mentioned, is that when people say the Liberty is twitchy, hard to land with its sensitive controls etc etc, they are saying that compared to other aircraft they have flown. I would say a good majority of OBA students have not flown before, and the XL2 may be their first aircraft to fly. Therefore to them it feels "normal" as they are used to nothing else.....just a thought
