Chris,
To my knowledge there are at least 6 of us, ex-AAC serving in the RAF. Before I would dare to give you an opinion on if you are better off or not with us, i'd ask which fleet you aspire to join, makes a big difference!!
If you want to change from Lynx to Support Helicopters - could be a case of frying pan to fire! If you want loads of hours, with a bit more comfort - try multi-engine, forget what the whingers say...tis a fairly good life.
The grass is always greener though, I do miss a busy Lynx 5 duty out of R850...............
