Hi Gang;
Doubt that they will swap the wings...the Mk5s can be a useful beast and all vibe restrictions will hopefully be removed soon...making role easier.
The 'K' situation with the 3 frames is reminiscent of the SFI 17/18 debacle of nearly a decade ago. We got through it then.
And there is no J/K pi$$ing from me either.
