As one of the recently departed from the N. Sea, I must wholeheartedly agree with mty colleague "BarsandStars"!
Drop the "H" and go for the "A", you can always "H" for fun with the big bucks that you earn from one of the airlines!
Before I started "H"ing, I remember an ex-military colleague of mine saying that having helicopter hours in your logbook was like having VD on your medical certificate (pre AIDS days!). Looks like he was right, and now I have 11500 VD certificates!
Good luck in whichever way you choose to go.
