The Arca-Swiss Cube C1, otherwise known as "The Cube" is a top of the line geared tripod head that I have had the pleasure of using now for the past two years. This head is capable of handling loads up to 85 lbs with ease. There are moments where I will cantilever my Arca Swiss 8x10 with a heavy lens, looking down at the ground and the Cube does not drift and can can be precisely tilted and pitched as if the load wasn't there.
