I don't use "quick" at all, because it is also not very useful for me.
What I do is that I use
	-f 
to select the various inbox folders on the quick run, and leave offlineimap
to sync all folders (no -f) on the long sync:

These are basically the first line of my mail-update script, if you are
interested in the full script (which also checks for connectivity etc)
let me know.

  UI=quiet
  longcommand="offlineimap -o -u $UI"
  shortcommand="offlineimap -o -f INBOX,Lists.debian-tex,Lists.texlive,Lists.texinfo,Lists.debian -u $UI"

where the -f lists all my default inboxes where mails are delivered via sieve or procmail.

I don't use that at all, but check internet connectivity as suggested in
the web site I linked to:
# Check connection status
if ! ping -c1 www.google.com > /dev/null 2>&1; then 
    # Ping could be firewalled ...
    # '-O -' will redirect the actual html to stdout and thus to /dev/null
    if ! wget -O - www.google.com > /dev/null 2>&1; then
        # Both tests failed. We are probably offline 
        # (or google is offline, i.e. the end has come)
        exit 1;
    fi
fi
