Sound like a QFI if you can't decide! Seriously the double Q tick is a very rare commodity, your first choice is what you will end up doing. To defend the dark side, QWIing is a lot of fun as well and you get involved with the tactics and op employment/development of the ac rather than doing endless QFI checks. TI- don't bother you'll just be a glorified JP. Everyone worth their salt has to work on the OCU or a CFS unit at some stage, the choice is yours.
