The other current F16s are close to minimum weight but could do a lot more work in the platform stiffness department.
The fact that you keep saying that doesn't make it true.
I posses several stiffness measurements and these do not support your statements at all.
In fact, the modern lightweight F16's are at their worst on a par with the modern F18's.
Nobody seems to bitch about stiffness there so why do you hold the F16 class to a different benchmark ?
