I have also tried contacting BA re: wind ratings, but was told they do not do any such testing. FWIW, I own the original Copper Spur UL2. I camped out at 12000' in a wide open basin during a fairly heavy storm. Max gusts from airports in the surrounding area were between 23 mph (at 9000') and 46 mph (5800'). The wind was hitting the vestibule of the tent and putting a serious bend in the center cross bar. I had to hold it up until about 2 am to keep the tent from flattening out. I know BA claims the HV model has a stronger pole system. After setting mine up today, I can confirm that the poles feel sturdier. I am not sure whether the increased height of the HV model will be a significant disadvantage. To be honest, I could not tell that the HV model was any taller. It does have much more headroom due to the walls being more vertical though. I am very happy with the my decision to upgrade to the HV model. If you do a search for "Copper Spur HV UL2" on youtube, you will find a quick preview/comparison review that I just posted.
