Al, I use at present 4 Keeney wind flags. I put those and 4 Grahams up for sale when I quit competition. The Grahams sold fast so I kept the Keeney. They work well for my purpose.
Your video reminds me that I have a video somewhere of my 75 and 90 yard flags both going 180 out from each other at the same time, also have one where the tails lift straight up without moving the vanes or prop. The wind does weird stuff at times.
