72' U.S. Towers TX-472 with a Force-12 C-3 about 10 feet above the top of the tower, inverted vee's fed from a common center for 40/80 at the top of the tower. The 80 is used on 30, and as expected it's several db down from a dedicated antenna. Don't have many problems working anything when I'm QRO, although I'm not normally the first one through...but sometimes life is sweet. Some of this last years expeditions I managed to work the first day. I think the high point of the year was working S79RR on 30 and 40 within about 10 minutes of each other. Also worked 3B9SP on 80.
