Anyone know what the preferred routing ATC likes for getting GA into/out of
BWI from/to the south.

I'd suggest filing airways whatever you do - they seem to insist on
clearing
you for them approaching the ADIZ.

I filed 8NC8 direct ANP once to see what I'd get - airways thru RIC and
PXT with vectors from Potomac approach to cut down the distance. I'm
going to try routing thru OTT next time per Michelle.
