The dolly is a Fisher 10 .I also mount a racing seat with a mitchell base onto the dolly. I did a few shots on "The Thing" that way. with the Klassen garfield rig (check his web site) I have rigged 2 inch pipe off the side of the chair,and rig two arms off of it . The trick with a seat is to get a foot rest organized using pipe. I also have a small aluminum cart that I used on 2nd unit "Hulk" that also uses the seat
Low mode scraping the ground at full gallop is very easy . Unfortunately i'm still on the vest with two Alexas more often than not. On the vest, I have to slide the gimble all the way up the post ,and slide it back before docking (awkward) I have had weight on the MK-V before .the gimble can take it. !80mm anamorphic with 1000 mag. on "The Thing" but at wide open it's harder for the focus puller
