Capt CH, As an old geezer who has done FW and RW, might I suggest a JAA fixed wing licence as your first step, followed (finances permitting) by the rotary wing licence. Most of the ground studies are common and this would probably be the simplestest route to follow. A few GA companies and corporate operators run both FW and RW and one of the most enjoyable jobs I've had, was operating a mix of both for a UK Company. Best of luck whichever you choose.
