Septerra,
Simple solution is to ring PSA. Don't wish to be the bearer of bad news but I know of a chap that went the same way as you and the answer was no. He was told that why should the ADF take a chance on the surgery being succesful ( I know it is 99% succesful), take a chance on him being recommended and then have to wait while he had the surgery and recovered from it. Remember if you are recommended you are only in the pool for 12 months. If they can not send you off to a service for 6 to 8 months it dosen't leave you much time in competition.
