Mutters, you speak the truth, the whole truth and nothing but the truth........in this case anyway. As to fixing their own cabs................................hahahahahahahahahahahahahahahahahahahahaha ect, ect so on and so forth.
If you are in a Tech trade it's best to wait until you reach Artificer to keep your options open (unless you're a crap tech of course). The needs of the AAC are usually greater than the needs of the REME, so once you read AGAI's and put your papers in, it usually won't get blocked. That said, watch out for Orderly rom full screws "losing" the application, or spineless OC's "filing" it so they don't lose a good tradesman.
I found the most obvious advantage of transitioning to REME Pilot was that I could be hated equally by Bats and Squawks alike, whilst carrying my flying pay past the uckers board in a wheel barrow, on my way to shag another busload of Nurses from Rinteln.
