I have used the crab method in 40kts 90 degree winds into Denham in a twin (that was the absolute limit)
I feel your examples will fall on deaf ears...
Again, shows lack of understanding of method, one of the beauties of wing down is that it is easy to compensate for changing conditions, you just vary the amount of wing down - how do you do that with crab?
Er...vary the amount of crab? Out of interest how would you land a 25m span glider in a strong xwind? Genuine question.
