So I now have three of these things: a #4, a #2 and a #2A (military issue).
My question is, why can I find alnost no info on these on the "standard" websites (APUG, LF Forum, Phot0.net, etc)?
They are very light, quite sturdy, pack down very small, etc. Sure, they don't lend themselves well to heavy heads, but they're perfect for most LF field cameras, etc. where you are typically leveling the camera anyway.
I dare say they're a much under-rated, if they're rated at all. They're not incredibly cheap, but they're cheaper than many other options that are more wobbly.
I've got all I need so I won't be fighting over any more . . . unless a #3 or #5 comes up . . .
