GFC's post was very interesting, but I would like to comment on one point he made, ie:
'Personally, I still fly wing low from about 200ft because I find it easier.......if the rudder isnt enough to keep you straight then there is no point in landing because you will end up running off the edge.'
The wind (and the crosswind) is often a lot stronger at 200ft agl than at 20ft. I have often been surprised at the amount of drift correction needed at 200ft or so which have lead to a reasonable landing, well within the authority of the rudder, due to reduction in wind strength and change of direction close to the ground.
I therefore try to make my decision to land or go around as late (low) as is safe when the crosswind is strong. This decision often depends on how gusty the day is as well as the usual factors like currency, type of aircraft etc.
