Pictures
I'm with Mr Cow here. Simple is best. Make sure they know that their property corners are in the correct location, and the bearing basis is just to fit their project. 30 yrs ago we all worked on assumed basis, then rotated to fit deeds or other surveys, and I still do to this day. If another surveyor wants my files, I'll send it. Enjineers or Architurckies, no....$$$$$ maybe. 😉
Pictures are good, but I often take the extra time to show the owner all the corners. Leave them as happy campers and they'll tell their friends what a great job you did. Some day the John Q's will understand what we do, but my 3rd yr of daisies will be about 2 ft tall by then.

This topic has been beat to death more than the 5th dead horse.
Basis of bearing is a measurable line between 2 found surveyed points. WGAS if it's N, S, E, NE or wherever. True North, Grid North, North from a hand compass (not good in MI - lots of iron), something from Aussie South, does not matter. Leave the record of what we did, and monument it.
The key point IMVHO is to be able for somebody else to duplicate what you did and why you did it. Pretty simple actually.
If you had two separate plats that showed the same line, but with different bearings posted (like maybe the centerline of a road right-of-way or something of that sort), you could show them that the line is the line. Whether you call it N 25-45-30 E, N 25-50-02 E, N 15-00-11 W, or Franklin, it is still the same line.
You can even set one map on a table, then set the other map over top of it and show that if you orient the one map to match the other map (and slide the top map so the common line matches up) you can show that each map has their own Basis of Bearings, but you have to rotate one to match the other if that Basis isn't the same.
I have a tough time explaining these things (along with coordinates, elevations, and making a good cup of tea) to my coworkers sometimes.
One of them there survey placks is WRONG!
Then there is Paul Schmook whose 1950+/- Surveys in the Town of Weott, Humboldt County look mostly like the Deed but he kind of fixed things as he saw fit, etc.
I've never done this, but I've always though to lay a drawing on a table roughly oriented to north and show it to the client. Then turn it about 30 degrees and explain that it's still the same picture, it's just oriented differently.

DOES THE PUBLIC KNOW WHAT A PROTRACTOR IS? I THINK THEY DO SNF IT IS NOT HARD TO EXPLAIN.
