I'm in the process of applying for an FTRS post pre-age 55 so I will be able to transfer to AFPS15 (as it is automatic) and will get to serve to 60 (or maybe even 65!!).
So if I get the job (and this works well for AFPS75 guys who are willing to drop 1-2 ranks) then "I'm alright Jack!". I meant that tongue in cheek, but it may give you another option to consider?
