Hi Jeff,
In fact i am suprised how well these two handle`s strong winds .. from all directions ...
Both are "equal" if i had to pick one of them what wind concern.
The difference between these two, as far i have experienced ; is in crosswind the Impact put it`s nose against the wind, and "almost" keep the track by itself , while the Integral is more like drifting sideways. This difference in behaviour is quite ok, and is more a matter of liking.
I did not qualify for the WC ; But we are a gang of buddies that are in an offensive position now !
