Thanks for the replies all. I am still going to do my absolute best to get through the retraining and recheck. I've put almost 15 years, 7K plus flight hours, and many thousands of dollars into this profession now, so I at least need to give it my best shot and try to get those four stripes (and pay off all of those flight school loans a bit quicker.)
That being said, being 32, I'm still at the point where I can make a big change if need be. Flying has always been, and continues to be, a struggle for me. I think this last failure has made up my mind as far as progressing to a major, and I don't plan on being a regional lifer. I will look into corporate, but if nothing materializes there I think my days flying airplanes are going to end soon.
