It gave me different types of experience (actual, bad wx, icing, turbine, high alt ops) that I can't get beating the pattern with a student. If anything it made me a more well-rounded pilot and instructor. I realize the airlines frown upon it, but logging it is the only proof I have that I have this kind of experience, and its some hours that may come in handy for getting my ATP or insurance minimums for some job down the road. I would suggest to anyone that has the opportunity to get some hours as SIC for a 135 to do so. Just remember its not going to get you an airline job, and if you show up to an interview with 1000 hours and 100+ of it is SIC in a King Air 90 then that may not look so good.
