About a week ago, I ordered an Induro CT-303 CF from B&H, and total cost ran to just about $500. It's advertised as supporting up to 44lbs. I already had a couple of heads I can use, including a Manfrotto ball head (055), and a Manfrotto MXHPRO-3W. I've pretty much opted for the Manfrotto 3-way, because its lightweight, and will support most anything, including my 4x5's.
The upper legs on the Induro are 33mm+, and the kit includes a second, short column, and spike feet option. Rig weighs in @ 6.1# (including Arca Swiss receiver and plate). I've tried it with my Linhof Technika III, and it seems rock solid. I also used it for my D850/70-200f2.8 and the images have been sharp with the VR turned off, in a brisk wind. I offloaded several Manfrotto/Bogen, and Gitzo aluminum tripods, and I only have CF in Manfrotto, Gitzo, and Induro remaining.
