Hi Jeanette, well I could tell you all kinds of tells...but what the gear sits on most of the time (35mm up to the 8x10 Korona) is the same Bogen 3021, with 3047 head. Have just started using a wooden Berlebach - older version, and I (blush) had to learn to tune it up (not sure why I figured it was made that way

) Anyhow, the legs are only one part of the story, the head is the other.
If you are happy with what you have and just need to put more solid legs under it, I would go with the 3021 (or 3221 if you like all black). DO pick up something to help you carry it, sling, carry handle (see web site or pick up a catalogue). IIRC you do trek out a bit for those waterfall shots, so a carbon (gasp the $$) might be a good idea, or look at one of the smaller wooden Berlebachs (Matt was using one at the workshop I bet). Good luck..and let us know which one found a new home
