Well all I can say is that my previous man at PMA said that he felt that a QFI tour after a Co's tour had, and I quote (hence the quotation marks) 'damaged peoples careers' - and he'd written a paper to that effect. I guess he might know. However, I know they are very keen to fill QFI slots at the moment so the advice coming out from PMA may differ now.
I also think it may well be the case that you can't get promoted without being above average as an ac captain so all those High/spec Recs you get as a QFI count for nothing until you've gone back to the front line and worked your way back to an above average assessment (Same deal if you change ac types). Probably knocks you back 3-4 years on average.
All very equitable.
