Thanks very much for your entry - we definitely appreciate the time and effort.
#6 - We definitely like the golfer. We recognize the use of the "pga" logo layout to give "authority", but given that we'll be using the logo for both our web site and letterhead, we're leaning more towards a horizontal layout and avoiding the silhouette. The font works in this context - we like sans serif.
We left comments for the other entries as well - if you can't see them but want to, let us know and we can post them here.
