I use a center column with a panning head (Sirui VA-5), while glassing. Then when it’s time to stalk/shoot, I’ll remove the center column and attach an Anvil 30 to the tripod yoke, by using a washer and bolt. The silver lever, used for height adjustment when using a center column, will clamp down against the tapered profile of the Anvil 30’s stem. It does so with relatively light tension. But will not flip up unintentionally. It’s really a non-issue. I’ve been really happy with my tripod setup this way. Easy to swap back and forth between glassing and shooting configurations.
