I'd seriously look at the Royal Navy if RW is your desire. You probably won't get RW if you join the RAF, and the officer slots in the Army Air Corps don't get much flying in after 1/2 tours.
The RN is a very good Service (forget the hostage cock-up) and the crack is superb. The flying is great, and most od the aircraft are single pilot with the exception of Sea King SAR and Sea King AEW. So you'll get lots of P1 from an early age, which you won't get in the other Services.
If you have the academic reqs (2 A levels) and the leadership skills you should give it a try. Costs nothing to try, and it might get you exactly what you want. Cruise over to the Mil Forum and have a look.
The RN will work hard to show you what you can do, and the recruiting officers will arrange ship and air station visits at no cost.
