Hi Trent! Not sure what brand you’re currently using, but RRS lever clamps have two positions, 90° open and 180° open. At 90°, a plate can be slid forward and back in the clamp, but if the plate has the safety screws on the bottom (RRS plates feature that), it cannot slide out of the clamp. Opening it fully to 180° is required to remove the plate.

I use their lever clamps on tripods (my bigger one has two, one on the leveling base to let me rapidly switch from ballhead to gimbal head, the other on the head itself). I’ve never had a scare with them. I do use a screw clamp in my monopod head, because I frequently carry that on my shoulder with a lens mounted, and there’s a reasonable risk of a lever catching on a backpack strap and getting pulled fully open. But otherwise, I prefer the ease and speed of a level clamp.
