Old Man's opinion.....get your pension....raise your kids...be home with the Wife....get as much experience/ratings as you can....then....look at the market.
Get your JAA (or whatever it is called when you get it) License....and with your language abilities, a government pension in your wallet, your kids all grown...you wife close to having a pension....then a 6/6 roster would work nicely until she gets her pension...then you two are set to do as you please. (All things being considered).
