Same here with the ball head, set the friction with just enough to let you move the scope around as needed, but holds it where you let it go.
The Oben-126 has a 44mm ball, and rated 26 lb capacity. It handles the 65mm Razor (3 lbs) very well.
It's burly enough to rest a 16 lb heavy rifle on too, if you are so inclined.
