Av8tr1,
I am in the same boat as you. I had my full Post-9/11 GI Bill after leaving the service and have every rating (airplane, seaplane, helicopter, glider, instructor, etc.). I went ahead and got my master's degree and *STILL* have about half my benefit left. I thought about getting a type rating, too, but ultimately decided that getting a second master's degree is about the only worthwhile endeavor at this point.
