The Miller CiNX 5 is our new favorite Head. With a payload capacity of 4.4 to 46.2 lb, 16 steps of counterbalance, 7 steps of drag, this head competes directly with the Oconnor 1040. 
But a few things we feel make it stand out. The top plate takes a direct fit of an ARRI standard dovetail, similar to the larger oconnor heads, this makes attachement fast and easy as well as reducing the need for various QR plates.. 
3/8" anti rotation (arri pin) mount points around the head for mounting accesories. 
And a flat base that can be setup for 100mm or Mitchell. 
Our kit includes the 100mm ball with super stable Miller legs.
