Hi,
I have an ultra-light CF tripod that I use for travel with the 4x5, a Technikardan 45.
Recently, I sold the chunky 3-way head to get something smaller and lighter, and I was thinking of a ball head.

I have always been dead-set against using ball heads with LF; I shoot quite a bit of architectural stuff, so the ball heads are/were poison.

But now I'd like to know if there is any ball head out there, small, compact that behaves somewhat like a 3-way head.
That is, can it be set to move in one axis only?
Would you trust it near your 4x5?

Please recommend anything you know of, regardless of price.

Thanks in advance.
