Many of my staff instructors are ex-Integrated schools and they tell me that all but the most talented trainees need 180-220 hours to get the CPL anyway. The "savings" in a 150 hour course are illusory.
As Okihara says, you can do plenty of Night, IF, Aeros, Tailwheel and other things in the 160 hours between PPL and a 200-hour CPL.
