My advice, get the CFI. Even if you never intend to use it, it looks good. Instruct while networking for a job you might rather have. I wasn't exactly keen on instructing however after being hired by my university during my junior year I realized that it was a flying job. I learned to love teaching things to students and there is no better way to meet prople and network than by instructing. It lead to several co-pilot jobs that lead to a regional airline a few weeks after graduation. If I had avoided instruction entirely I would not have had the opportunity to fly King Airs and Navajo's due to the requirements for those jobs including a CFI/MEI. Why did they require a CFI? The chief pilot said it showed dedication to the profession to have a CFI license. At the airline I work for, a CFI/CFII/MEI will get you through the door a hell of a lot quicker than several hundred hours of rented twin time. One can argue all day as to which is more important to the job, but the fact is more regionals like candidates that are "working" in the industry. Make your life easier, get the CFI. I know I sound like I'm preaching but I just told my wife the very same thing. She doesn't really want to get it either but expects the same company that hired me to fly co-pilot in a King air to let her fly right seat as well. I told her to persue the CFI rating while she waits for calls to fly right seat. I hope she listens to me as right now she thinks I'm stupid.
Actually flown: EMB-120 EMB-145 B717 B737 B757 B767
