Thanks Bealzebub, I appreciate your advice.
Someone that I know recently secured a 737 job with 230 hours and a three week-old MCC certificate. This development made me question whether or not I'd be doing myself more harm than good by getting into instruction. It's not that I don't want to or that I'm desperate to do fly a nice shiny jet without having to wait for it - as long as it's not to my detriment I'm very keen to instruct.
