Had the green (monster) version ages ago...used it almost exclusively with a 210 f/9 Computar. Acquisition was inspired by Cole Weston...who'd walked me around his, and related how - whenever he and his camera got caught out by a big wave...he'd simply hose the green beast off and let it dry out a bit.

Ultimately did not warm up to 8x10, and ended up using it mostly for jobs where clients demanded 8x10 chromes. I did like the C-1 for its sturdiness and utility. But to carry it around now - as I'm about to hit 70? Heck...my 11x14 (which I still do carry around) is lighter!
