Actually, I totally disagree. You neither have the knowledge nor experience to structure your hour building effectively, and for too many people it becomes a case of just boring holes in the sky. Whether you learn anything or not is left to chance. That is totally inappropriate for what is supposed to be professional training. It is one of the major reasons why integrated courses (plus CTC) are preferred by some airlines, and why the MCL has been initiated.
If you want to just go and fly round and round looking at the view, stop at a PPL and spend the rest of the money enjoying yourself!
