Ditto… I 3D printed an adapter for a RRS ball head. Works great.I have a BOG and it does the job, fully adjustable , ball head on it, legs can go almost straght out, and lock in different positions, they are on Amazon. Check them out. It has beafy legs, and it's rock solid, got mine on sale, for around $180.00, has the death grip top on a ball joint, and made a adaper in my machine shop to clamp it quikcly, it's out standing.
