I got to hand it to Arca-Swiss, they make superb products. I dont know if this was officially announced yet by them (I know I was the very first person to buy one about three weeks ago), but I just got a hold of their new Cube with a built in click-pan top. (See pic below.) You can pan freely or incrementally in degrees of 6, 7.5, 10, 12, 15, 20, 24, 30, and 40. As expected, no play what so ever in the click stops.
The price was decent too, around $1800, although with how the value of Euro and dollar is changing, it could be different.
I reached out to Rod in April looking for a better solution to the NovoFlex adapter and was told to wait on getting anything. He reached out to me the day they arrived in the country. There is also version for the D4 head too, which I assume is priced lower.
