BlitzB, as Bill mentioned, we'd be happy to help. One thing I thought of which may help...

If you open up this folder on your Mac:
<your home folder>/Library/Application Support/OmniFocus

and do a Get Info on the "OmniFocus" or "OmniFocus.ofocus" file you see in that folder, how large is it? That info will help us figure out if there's a large quantity of data in the app which isn't visible (completed actions, for example) or if there are any file attachments in there. Either of the above could cause the amount of data being synced to the phone to be very large, even if there are a small number of visible projects/actions/contexts in the database...
