Found Borgan 522, which only for 501 head...I want 700RC2, seems no option?
Canon ZR-1000 looks nice, should fit smaller head, but it works for Canon camera only, am I right?
So, what do you use for x10/950?

I use the Varizoom Pro-L but it's large....

I believe Bogen makes a 522a LANC controller for it.
