I use a Tiltall with the head removed and exchanged for a Linhof Profi II. I bought 1-1/4" aluminum tube stock, made a compression fitting on one end with a bunch of stacked washers, drilled a hole in them to accept a 3/8 screw, and attached the ball head. It'll take a ridiculous beating without coming apart. (I made a mock-up with leftover tube stock and a brick bolted to the compression fitting - smashed it on the ground, and it still held. Point being; the Tiltall legs are more than capable for what the head cannot hold, and with your own ball head, a mallet, and some files, you can fix what I'd consider to be the weakest link in the chain.
