Hi Greg,
What is "Image Assistant"? - sounds interesting.
A lot of the nature recordists are using omnis. Are you considering
free space or a barrier?
Most of my omni experience has been with small lavalieres using a tree
or rock as a barrier. For trees I'd say 25cm diameter would be a good
happy medium.
Here's one example from my sound journal:

The wl-183s mounted about 8 feet up in a 9" diameter pine.
