G'day Logan, you mention grab and go. Depending on your other circumstances, you may want to consider an FC76 DC, perhaps even the split tube version. A weight saving of 40% on the OTA and suited for carry on luggage if you did want to take it on a flight. Fluorite element at rear so better protected. Not sure if this is of interest, but I am sure the FS78 is a superb instrument. Just a little hefty for a 3" by today's standards.
