But what does this really mean? My gut tells me that in that configuration, it does NOT have the same sprightly acceleration, may not be capable of greater than 50 degree AOA, pedal turns etc.. It's simple physics. A heavier aircraft is going to have a much lower thrust to weight ratio, thus affecting many of those parameters.

Is this correct?

It's not just the F-35 though, this would be true of all airframes. Flankers included. In fact, it's going to be worse there with what, 25,000lbs of internal fuel in some cases? The F-35 cadre probably isn't too worried, given its massive SA, stealth and EW advantages over other jets...

Ability to fly at high angles of attack is about aerodynamics, weight has practically nothing to do with it. F-35 is very capable of very high angles of attack at any internal load, and probably at almost any external load.

Actually, the heavier load the plane has, the higher angle-of-attack it WILL by flying on average, because at heavier load, plane needs more lift, and that lift is achieved by using higher AoA.

Other airplanes, carrying underwing heavy weapons, will suffer significant handling quality degradation when fully loaded, made worse by partial downloads resulting in lateral asymmetry. F-35, with with internal stores close to the centerline, should not be bothered by such limitations.
