There are still lots of PPL holders building 100+ hours to qualify for a CPL course, when you could be spending your money more profitably by adding an IR to your PPL. You only need 50 hours of Cross Country flying post PPL so you can gain an IR at around 150-170 hours. The CPL course is reduced to 15 hours for applicants who already hold an IR, so you finish up with a CPL-IR at 200 hours rather than 250 hours. Why bore unnecessary holes in the sky?
