Perhaps ungainly is a better word. The C33 weighs 6 pounds. Swap out the 80 mm lens and add the 180 mm one and the grip and you're around 10 lbs. Try walking about for more than a few minutes with this weight around your neck. A wonderful camera when used on a tripod. I tend to think of TLRs in terms of contemplative photography where there is no time constraint.
That reminds me of my old Mamiya RZ67 and why I sold it.
