<<In these conditions, you simply MUST go wing-low>>
I don't agree. In these conditions you fly the A/C in accordance with the manufacturers approved technique. That may or may not give you the option of 'wing down' as opposed to 'crab'.
'Kicking out the crab' leads one to imagine abrubt control inputs to the uninitiated. 'Pushing off the drift' might be a better description; that combined with into wind aileron whilst entering the flare should lead to a successful landing on the C/L.
Dancing on the rudder pedals is most certainly not a recommended technique on any swept wing jet I've come across. A measured amount of rudder to push off the drift is recommended.
<<those who advocate it haven't tried it in high x-winds/gusts.>>
Actually I believe a lot of us around here have indeed tried it in x-winds with gusts up to the x-wind limit. Certainly in the northern hemisphere winter one gets to try it rather a lot.
And finally you say: <<You must accept an off centerline landing>> I don't accept such a landing, and nor I believe do most of my colleagues.
