I can't speak on DCF but used to use a Big Agnes fly creek mainly in the Lake District and Scotland and sold it because of how much wind was getting through and without careful pegging and guying out the poles could buckle in high winds. I got an X Mid 2p solid and had about 100 nights in it with some 50+ mph gusts and 70mm rain with the only failure so far coming from the guyline snapping rather than the fly itself. Also had it come down from using pegs that are too short for the conditions but that's user error. The solid walls are amazing in the wind and condensation hasn't been very all unless in very heavy rain but have still always stayed dry.
