These would work great too. The bigger the ball the better, anything over 35mm seems to be good enough.That’s a big tripod - if weight isn’t a prime concern, a used Arca-Swiss Monoball head is big (55mm ball) and stout. It’s an old design and these were the original professional quality ball head and the company originally came up with Arca rail. Used, a good deal is $100, but $150 is more common. Our family must have six of these on big tripods we don’t carry around for glassing and I’ve started using one shooting with a plate.
