Well your CFI is always a Back up should your Flavor of the Day Regional TANK you can always instruct on the side..I am partial to the CFI experience because I learned more by instructing for 3 years than any RJ course will teach you.. remember what ever you need to know about the RJ the company will teach you Having your CFI in my eyes tells me you are Teachable and thus not much of a Liability ... Get your CFI CFII MEI AGI IGI its all worth it and the study habits you get from getting them will hopefully last a lifetime..
