brother, now doubt 17 is better then 16 but i think that FIA is a organized and better department then ANF. if u r on training i guess you are watching the functions of AD ANF and futher u will see when u wl post out in some other ANF office u wl see that there are many hurdeles and limited scope, my friend is also in ANF so i have knowledge abt deptt. and every on is not lucky like u have two options. in my point of view FIA is 100 time better then ANF and u will see soon.
regards
