I figured out how I was able to get the max upward tilt out of the 410 head: Raise the center column. (Although this only makes the whole rig more unstable).
Otherwise (on my tripod anyhow) the controls can bump against the top of the tripod. The 410 head allows you to tilt 30 degrees up. I'll experiment with turning the camera around. The head turns down 90 degrees.
According to the specs, a 410 head will support up to 5 kg or 11.1 pounds, but a 5x7 Sinar P weighs 8.2 kg, or 18 pounds.
So I'm over-loading it by... 75%. Oops
Try facing the camera the other way and though it's a bit contortionisty you can get even more upward tilt. Just have to handle the controls backwards.
The prune industry used to be big around here, but most of the orchards have been converted to vineyards.

Greg, The tones of your image are awesome. The broken symmetry is interesting, but with the tree so dominant I would be interested in seeing compositions where it is off center too. I definitely understand the reason for a square crop as presented.
