Ex Mil RW too and have had a very varied, satisfying and full civilan career to date flying helicopters. But the world is very different today as is the helicopter industry and I could not recommend a RW flying career to anyone. If you are interested in flying then a fairly safe bet would be to train as a prospective airline pilot. Until the automatons take over it would be an interesting and fairly lucrative way to earn a living.
I have done my share of offshore flying but have managed to avoid it mostly. Why anyone would think that flying a fully-automated helicopter over hostile (generally cold) seas for hour after hour in a survival suit is a satisfying way to spend your working life is beyond me.
