Not really true - the C200 is actually just a bit lighter than the 1DX MKII.

I just read the comments- it's too heavy for the Ronin-S, he had to use warp stabilizer to fix the footage. If you want to go one-handed with a gimbal with 4K60 with decent low light and good AF, there's really only one option right now (and it's not the 1DX II: I got the 1DX II to work on the Moza Air 2: it's too heavy for anything other than short takes). When I realized even the 1DX II was too heavy without an arm+vest or an overhead backpack dork-master 5000 it accelerated my goal to downsize camera gear further (to X-T3 / A7x / EOS R size).
