(Personally – and it is just a personal opinion – I think that the Taipans are missing a golden opportunity by not “upgrading” their specs to full F16 as a class. It would achieve the greatest outcome with the minimum disruption, and breathe new life into the class that would see them at the “forefront” for many more years to come).
Also my opinion mate...... If I was the powers to be, in the class, this would be the approach I would push for.
