I am thinking about the same things Tech. It seems Doug is right, and usually is; A combination of FBO and large school(Academy) is the right mixture.
Right now, I plan to try and get as far as I can at the FBO level, but only want to get my PPL and IFR rating. Some work towards a commercial is fine, but I am not sure I want to finish it at the FBO.
After that, it seems like an academy will not only speed things up, but also provide more bang for your buck. I do not want to show up to my first regional interview with a measly 100 hours ME time. My personal goal is more like 400. Also, for me personally, age is a factor as I am 31 right now. I cannot really afford to dilly dally for 3-4 years getting all my tickets and hours at an FBO.
